  Polycarbonate (PC) is an engineering plastic with excellent comprehensive performance, and its output is second only to polyamide (PA). It has excellent properties such as impact resistance, dimensional stability, heat resistance, and transparency, and is widely used in electronic and electrical appliances and the automotive manufacturing industry. Compared with ABS, PC/ABS alloy can improve heat resistance, impact resistance, and improve surface defects such as depression and warping of products. Compared with PC, it can improve fluidity, improve processing performance, reduce the sensitivity of products to stress, and reduce production costs.   Taking automotive applications as an example, ABS/PC alloy is a material that is more suitable for automotive interior parts. It has excellent heat resistance, mechanical properties, and good processing fluidity. The Vicat softening temperature of automotive dashboards made of ABS/PC alloy can reach 110-135℃. In addition, it has good coating properties and adhesion to the covering film. The dashboard does not require surface pretreatment and can be directly sprayed with soft topcoat or coated with PVC film. ABS/PC alloy is also used to manufacture automotive parts such as parts around the dashboard, antifreeze plates, door handles, underflow plates, brackets, steering column covers, decorative panels, air conditioning system accessories, etc.   Ps: The above news come from website.

  There are many advantages of high temperature resistant PC plastics, and the most prominent advantage is its super high temperature resistance and impact resistance. For example, when producing parts such as instruments and meters, high temperature resistant products are needed, and high temperature resistant PC plastics are a better choice. The absorption rate of high temperature resistant PC plastic products is very low, which will not increase the difficulty of work for workers. However, in the process of using high temperature resistant PC plastics, it is necessary to dry and bake the materials to greatly improve the quality of the products.           The wear resistance of high temperature resistant PC plastics is very high. Compared with ordinary products, high temperature resistant PC plastics can play a high wear resistance in the production process, and will not affect the thickness of the product due to certain operating processes, thereby affecting the overall quality. However, this product is prone to melt cracking, which requires the staff to strictly control the molding conditions of high temperature resistant PC plastics during work. Each batch of plastic parts must be cooled, and the quality of plastic parts should not be affected due to improper handling.     Ps: The above news come from website.        

  Today, as the environmental protection wave sweeps the global manufacturing industry, Chinese plastic companies are reshaping the competitiveness of the industry through innovative recycling technologies. Post-consumer recycled plastics (PCR), as a key carrier of the circular economy, have become a green pass for leading domestic brands to break into the international market. Take the latest food-grade TPE launched by Avant as an example. This material containing 25% recycled PP components not only passed the strict review of the US FDA and obtained a no objection letter (NOL), but also broke the industry prejudice that "recycling means low quality" with a hardness performance of 65 Shore A. Its birth confirms the application potential of PCR materials in high-end scenarios such as toothbrush handles and food containers, and provides a replicable technical template for Chinese plastic product companies.     International regulatory dynamics are accelerating the compliance process of PCR materials. In the second quarter of 2024, the US FDA intensively approved 12 recycled plastic notices, covering a variety of polymers such as PET, PP, and PS. Among them, the high-density polyethylene (HDPE) beverage bottle caps of Germany's Gneuss and the chemically recycled PET of the Mexican Alpek Group highlight the parallel development of physical recycling and chemical recycling technology routes. These certifications strictly limit the conditions for the use of materials: for example, when the recycled polypropylene of the Indian Pashupati Group is approved for use in fresh fruit and vegetable packaging, it must meet the E-G temperature specifications (i.e., refrigerated to room temperature environment). If domestic companies want to enter the European and American markets, mastering these grading standards will become the key to breaking through.     The value chain construction of plastic recycling certification requires a systematic layout. Starting from the traceability of raw materials, brands need to establish a transparent recycling collection system to ensure that PCR components can be traced back to food contact grade waste plastics. The production process must pass certifications such as the GRS Global Recycling Standard, which requires at least 20% of recycled materials to obtain access qualifications, and the use of certification labels must be increased to more than 50%. It is worth noting that a modified plastic company in Dongguan successfully entered the Coca-Cola supply chain last year after winning the GRS certification with its "bottle-to-bottle" rPET technology, confirming the recognition of the certification system by international brands.     Technological innovation is breaking the performance bottleneck of PCR materials. The compatibilizer formula developed by a Ningbo company effectively solved the problem of molecular chain degradation caused by multiple recycling, and increased the impact strength of recycled HDPE by 40%; while the devolatilization technology of Shanghai Institute of Chemical Industry successfully removed the odorous small molecules in the recycling process. These breakthroughs have pushed PCR materials to extend from low-end packaging to high-value fields such as automotive parts and electronic appliances. According to industry forecasts, the scale of China's recycled plastics market will exceed 20 million tons in 2025, and companies that have laid out technical patents in advance will occupy the commanding heights in the competition.     For plastic brands planning to expand their international business, it is recommended to adopt a three-stage strategy: initially, choose a single category of PCR resin (such as rPET) with mature technology to enter, and establish market trust through FDA no objection letters or GRS certification; in the medium term, jointly build a closed-loop system with recycling companies, such as toy manufacturers cooperating with community recycling outlets to obtain food-grade waste plastics; in the long term, explore chemical recycling technology to convert mixed waste plastics into oil-based raw materials to achieve infinite circulation. Only by integrating environmental certification into the entire life cycle of products can Chinese plastic brands truly achieve green premiums.

  With the mandatory implementation of the "Technical Specifications for the Use of Recycled Plastics in Household Appliances" (T/CHEAA 0034-2024) in January 2025, home appliance companies must achieve a maximum of 20% post-consumer recycled plastic (PCR) addition ratio. This policy is driving deep changes in the industrial chain. A modification factory in South China uses molecular-level purification technology and a three-layer melt filtration system to remove 5-micron metal impurities in PCR, increasing the transmittance of recycled polypropylene to 92% and the impact strength to 98% of the original material standard. At the same time, packaging companies in East China introduced AI visual sorting equipment to increase the purity of PET bottle recycling to 99.2% and reduce raw material costs by 30%. The key to technological breakthroughs lies in overcoming the performance bottleneck of recycled materials. The nano-calcium carbonate reinforcement system developed by a leading company successfully increased the bending strength of PCR-ABS materials to 65MPa, replacing imported raw materials for high-end air-conditioning shells. It is worth noting that GRS global recycling standard certification is becoming a market pass - certified companies need to establish a full-link traceability system, and each batch of goods must match the TC transaction certificate, covering 12 types of certification documents such as raw material procurement contracts and transportation documents. A daily necessities company in Ningbo has achieved a 40% increase in export orders with GRS-certified food-grade PCR-PET lunch boxes. The industry reshuffle has accelerated. A Dongguan injection molding factory used uncertified PCR materials, resulting in a product brittle cracking rate of more than 15%, resulting in losses of more than 3 million yuan; while leading companies have used high-performance marine plastic (OBP) technology, combined with molecular chain repair technology to increase the impact strength of recycled PET by 3 times, and cooperate with UL 2809 environmental certification to open up the high-end market. With the GB/T 16288 standard forcing products to be labeled with recycled content, China's plastics industry is shifting from passive compliance to technology-driven value creation.

  Under the global environmental protection wave, post-consumer recycled plastics (PCR) are becoming the core competitiveness of China's manufacturing. The "Technical Specifications for the Use of Recycled Plastics in Household Appliances" (T/CHEAA 0034-2024), which will take effect in January 2025, requires that the proportion of PCR added to household appliances be up to 20%. This policy forces the industrial chain to upgrade. A modification factory in South China uses molecular-level purification technology and three-layer melt filtration to remove micron-level metal impurities in PCR, so that the transmittance of recycled polypropylene is increased to 92%, and the impact strength reaches 98% of the original material. Relying on the AI ​​visual sorting system, packaging companies in East China have increased the purity of PET bottle recycling to 99.2%, reducing raw material costs by 30%.      The key to technological breakthroughs lies in breaking the performance bottleneck of recycled materials. The nano-calcium carbonate reinforcement system developed by a leading enterprise has enabled the flexural strength of PCR-ABS materials to exceed 65MPa, successfully replacing imported materials for high-end air conditioner shells8. What is more noteworthy is that GRS global recycling standard certification is becoming a market pass - companies that pass this certification need to build a full-link traceability system, match each batch of goods with a TC transaction certificate, and provide 12 types of certification documents such as raw material procurement, transportation, and recycler qualifications. A daily necessities factory in Ningbo has increased its export orders by 40% with its GRS-certified food-grade PCR-PET lunch boxes.     The industry reshuffle has quietly taken place. A Dongguan injection molding factory suffered a loss of 3 million yuan due to the use of uncertified PCR materials, resulting in a product brittle cracking rate of over 15%; and Veolia Huafei, through the high-performance technology of marine plastics (OBP), jointly with the Chinese Academy of Sciences team, used molecular chain repair to increase the impact strength of recycled PET by 3 times, and combined with UL 2809 environmental certification to open up the high-end market4. With the GB/T 16288 standard requiring the labeling of recycled content on products, the green transformation of China's plastics industry is shifting from passive compliance to technology dividend-driven.

  The EU's "Packaging and Packaging Waste Regulation" (PPWR) sets a strict threshold: from 2030, the content of post-consumer recycled materials (PCR) in plastic packaging must reach 30%, and those who fail to meet the standard will be subject to a plastic tax of 800 euros per ton. This policy makes GRS Global Recycling Standard Certification a key breakthrough for Chinese companies - a plastic bag factory in Dongguan has relied on this certification to enter the supply chain of fast fashion giants with its 100% PCR composite packaging bags, with annual exports exceeding 180 million yuan.   The core value of GRS certification lies in building a reliable traceability system. Taking recycled plastic bags exported to the EU as an example, companies need to match TC transaction certificates for each batch of goods and provide 12 types of certification documents such as raw material procurement contracts, transportation documents, and recycler qualifications. A packaging company in Xiamen uses blockchain technology to shorten the traceability cycle from 7 days to 2 hours, greatly improving customer trust. The more far-reaching impact is in profit reconstruction. A daily necessities factory in Ningbo transforms PIR injection molding scraps into food-grade tableware, and the product premium reaches 25% after passing GRS certification; a material company in Shandong enters the UK infrastructure market with UKCA-certified PIR insulation boards, and its profit margin increases by 18%.   Technological innovation and certification are forming a synergistic effect. The high-performance technology of marine plastic (OBP) developed by the Chinese Academy of Sciences team increases the impact strength of recycled PET by 3 times through molecular chain repair, and opens up the high-end market with UL 2809 environmental certification. When TC certificates become the hard currency of green trade, China's plastics industry is moving from the OEM model to a new battlefield for standard setters.

  The "Technical Specifications for the Use of Recycled Plastics in Household Appliances" (T/CHEAA 0034-2024), which came into effect in January 2025, put post-consumer recycled plastics (PCR) in the spotlight - home appliance companies must achieve a mandatory quota of up to 20% of recycled materials. This policy is forcing the industrial chain to upgrade: Haier's molecular purification technology removes micron-level impurities in PCR through three-layer melt filtration, and its modified PCR polypropylene is used in the inner barrel of the washing machine, with an impact strength of 98% of the original material standard, reducing carbon emissions by 1.8 tons per ton.   The key to technological breakthroughs lies in solving the bottleneck of recycled material performance. A modified factory in East China uses a nano-calcium carbonate reinforcement system to make the flexural strength of PCR-ABS material exceed 65MPa, successfully replacing imported materials for air conditioner shells; packaging companies in South China use AI visual sorting systems to increase the purity of PET bottle recycling to 99.2%, reducing raw material costs by 30%.   The market reshuffle has already begun. A Dongguan injection molding factory used uncertified PCR materials, which resulted in excessive brittle cracking of products and caused losses of more than 3 million yuan; while companies that have passed GRS certification are rapidly gaining market share - Ningbo Lishi's food-grade PCR-PET lunch boxes can provide complete TC transaction certificates, and export orders will increase by 40% in 2024.   With the GB/T 16288 standard requiring the labeling of recycled content on products, a policy-driven green transformation is shifting from compliance costs to technological dividends. When air conditioner shells carry 30% of post-consumer plastic components, the sustainable transformation of China's manufacturing has penetrated into the supply chain.

  In early 2025, Haier Recycling and Toyota Tsusho reached a strategic cooperation to jointly develop automotive-grade PCR recycled plastics with a purity of up to 99.9%, directly addressing the pain points of core components of new energy vehicles. Traditional recycled plastics have long been difficult to meet automotive safety standards due to their high impurities and unstable performance. Haier relies on the "five-network integration" recycling network covering the whole country and the Qingdao interconnected factory to achieve 100% removal of metal impurities through cutting-edge sorting and cleaning technology, with an impurity rate of less than 0.2%, and almost zero attenuation of recycled material properties. This breakthrough enables PCR materials to replace virgin plastics for key components such as bumpers and interiors, reducing carbon emissions by 21% for a single vehicle.   The core competitiveness of this cooperation lies in the closed-loop traceability system: Toyota Tsusho provides global chemical compliance support to ensure that materials comply with the laws and regulations of various countries; Haier controls the entire process of home appliance recycling-disassembly-regeneration to ensure a large-scale and stable supply of raw materials. Its annual PCR production capacity of 30,000 tons is accelerating the replacement of imported products such as Covestro. Wanhua Chemical, Life Recycling and other companies are also simultaneously deploying modified PCR-PC/ABS alloys to enter the automotive-grade structural parts market. The EU ELV regulations require that the proportion of recycled materials in new car plastics by 2031 should be no less than 25%. Shanghai Aossel invested 300 million yuan to build a 200,000-ton PCR zero-carbon plant. Through intelligent sorting and carbon footprint systems, it provides localized solutions for the implementation of regulations and promotes the green transformation of the automotive supply chain in China, Japan and South Korea.

  In February 2025, Polyplastics announced the launch of the world's first 40% glass fiber reinforced PIR recycled PPS - DURAFIDE® rG-PPS, reconstructing the recycling logic of super engineering plastics through the "Open PIR Program"25.   The technical breakthrough lies in the "re-blending" process:   Source control: only self-produced glass fiber reinforced PPS scraps are recycled to eliminate raw material performance fluctuations;   Deep metal removal: 100% removal of metal impurities in the previous process to ensure electrical insulation;   New material compounding and strengthening: recycled materials and virgin materials are scientifically blended and passed the quality test equivalent to new materials5.   This technology reduces the product carbon footprint (PCF) by more than 30%, and will be first supplied to the Japanese market after mass production in December 2025. Polyplastics simultaneously develops high-filled grades and plans a global "local production-local consumption" recycling chain to meet the mandatory requirement of 25% recycled plastics in the EU ELV regulations5.   Differentiated value of PIR and PCR:   Source difference: PIR is derived from factory production waste (such as nozzles, defective products), and its quality stability is better than PCR plastics recycled after consumption;   Application scenarios: PIR recycled PPS is suitable for high-reliability fields, such as new energy vehicle battery brackets and 5G base station precision components, while PCR focuses more on daily necessities and packaging8.   China's inspiration: Cangzhou Dahua's continuous production of silicon copolymer PC and Wanhua Chemical's PCR modification technology show that domestic companies are learning from the PIR model to tackle high-end recycled engineering plastics and promote 100% recycling of PA, PC, etc.

I. Global Policies Drive Market Change   The plastic circular economy is ushering in an unprecedented policy dividend period. Starting in 2023, many countries and regions around the world will begin to implement mandatory recycled plastic content requirements, pushing the PCR plastic market from a "moral option" to a "compliance requirement". The UK's plastic packaging tax, which will be implemented from April 2024, stipulates that plastic packaging that uses less than 30% recycled materials will be subject to a tax of £200 per ton1. The EU's Packaging and Packaging Waste Regulation (PPWR) requires that all plastic packaging contain at least 50% recycled materials by 2030. In the field of electronics and electrical appliances, China's "Specifications for the Use of Recycled Plastics in Electrical and Electronic Products" was issued in 2023, clearly stipulating the target addition ratio of recycled plastics in products such as washing machines and air conditioners6. This policy will directly stimulate the growth in demand for PCR engineering plastics, especially high-end materials such as PC and PC/ABS. Driven by the policy, the PCR plastic market has shown explosive growth. According to Grand View Research, the global PCR plastic market will reach $89.5 billion in 2030, with a compound annual growth rate of 11.2%. Among them, the electronics and automotive industries will become the fastest growing application areas, accounting for more than 40% of the market share. 2. Technological innovation breaks through performance bottlenecks   Upgrade of sorting and cleaning technology Efficient sorting is the basis for obtaining high-quality PCR raw materials. The new generation of sorting technology has achieved molecular-level identification: AI visual sorting system: Identify plastic type and color through machine learning, with a sorting accuracy of >99% Laser induced breakdown spectroscopy (LIBS): Accurately identify additives such as bromine-containing flame retardants Hydrophobic flotation: Separate PE/PP mixtures using surface tension differences For severely polluted post-consumer recycled materials, the ZSK FilCo compounding extrusion system developed by Coperion achieves one-step filtration and modification. The system first melts and homogenizes the waste plastic, then removes contaminants through an integrated filter, and finally re-feeds it into the modification zone to add reinforcement materials2. Compared with the traditional two-step method, this technology reduces energy consumption by 50%, while avoiding polymer degradation caused by secondary melting. High-performance modification technology Nano-enhancement technology has made a major breakthrough in the field of PCR plastics. Studies have shown that adding 0.8-1.5 parts by weight of nano-zirconia and 2-3 parts by weight of polarized particles can increase the whiteness of PCR PC to 98.6% and the transmittance to 91.2%8. This breakthrough has enabled PCR materials to be successfully applied to fields with strict requirements on optical performance, such as backlit keyboards of high-end notebooks. Chemical recycling technology has also made progress. The chemical depolymerization process developed by Covestro can depolymerize waste PC products into monomers, and the performance of the recycled materials is exactly the same as that of the original materials. This technology has been commercialized with an annual processing capacity of 25,000 tons. Innovative alloy development Weather-resistant enhanced PCR PC/ABS: Adding hollow silica microspheres (0.3-0.8μm, hollow ratio>90%) to improve weather resistance High-flow PCR PET/PC: Controlling ester exchange through reactive compatibilizers, the melt index is increased by 35% Flame-retardant halogen-free alloy: Suzhou Waldorf SustainX® series achieves 1.5mm V-0 flame retardant grade

  On April 21, Shanghai Osel Materials Technology Co., Ltd. and Tianjin Economic Development Zone officially signed a letter of intent for investment cooperation, and will invest in the construction of a PCR (Post-Consumer Recycled material, post-consumer recycled material) plastic intelligent fine sorting and high-end granulation digital zero-carbon factory project in the northern part of Nangang Industrial Zone. This project will create the largest "car-to-car" high-value closed-loop utilization system in China, help the development of the circular economy, and set an international benchmark. The total investment of the project is 300 million yuan, covering an area of ​​100 acres. After completion, it will produce 200,000 tons of PCR plastics annually. Among them, the first phase will invest 100 million yuan, cover an area of ​​30 acres, and plan to produce 50,000 tons of PCR plastics annually. The project will join forces with world-renowned industry chain partners to jointly promote the localized closed-loop recycling application of automotive plastics, help the automotive industry effectively respond to the challenges of "carbon tariffs" and "green trade barriers", and promote China's manufacturing to connect with international ESG standards. Shanghai Aosel is headquartered in Songjiang, Shanghai. It has established several front-end processing bases for renewable resources across the country. It has long been committed to the research and development, production and sales of high-quality, low-carbon PCR plastics (such as PC, ABS, PP, PA, PMMA, etc.). Its products are widely used in high-end new energy vehicles, high-end consumer electronics, smart homes, high-end lighting and other fields, covering the complete ecological chain of recycling, sorting, crushing, cleaning, granulation, inspection, etc. As one of the earliest low-carbon and environmentally friendly enterprises in China to realize the processing and utilization of car lights and have scale effects, Aosel is the main drafting unit of my country's national standards for recycled PC, PP and ABS, and has more than 30 patents. Its products have also obtained the world's first PCR content verification certificate for automotive recycled materials, as well as the world's first car light recycled material source certification certificate issued by TUV and UL 2809, with significant industry influence. The implementation of this project will not only inject new momentum for green and low-carbon development into the Nangang Industrial Zone, but will also accelerate the agglomeration of regional high-end new materials industries, help TEDA create new international competitive advantages in the field of green circular economy, and provide solid support for the green transformation of China's automotive industry.

Qingdao Hailuyuan Recycling Technology Co., Ltd. (hereinafter referred to as "Haier Recycling"), a subsidiary of Haier Smart Home, and Toyota Tsusho (China) Co., Ltd. (hereinafter referred to as "Toyota Tsusho") held a strategic cooperation signing ceremony in Qingdao. The two parties will cooperate in the plastic recycling business in the home appliance and automobile fields, and jointly develop high-quality PCR recycled plastic products with a purity of up to 99.9% to establish an automotive recycling supply chain to meet the growing demand for recycled plastics in the automotive industry and jointly promote the high-quality development of the plastic circular economy industry. As a green and low-carbon new material, PCR recycled plastics mainly come from plastics extracted from secondary recycling of household appliances, automobiles, etc. after daily consumption. However, according to relevant data statistics, in 2023, driven by multiple favorable policies, the recycling rate of waste electrical and electronic products will be 37.17%, a year-on-year increase of 3.72%. Most of the rest are dismantled in an irregular manner or enter the second-hand market after refurbishment, which not only pollutes the environment but also causes waste of resources. On the contrary, if the waste home appliances are recycled and disassembled and applied to the fields of automobiles, daily chemicals, OA, etc., it will not only reduce environmental pollution, but also help save resources. In this cooperation, Haier Recycling and Toyota Tsusho will give full play to the advantages of their respective fields to jointly build a high-quality PCR supply chain in the automotive industry. Toyota Tsusho is a wholly-owned subsidiary of Toyota Tsusho Corporation, a member of the Toyota Group, and is an industry leader in automotive carbon neutrality and sustainable development. In April 2024, the original metal resource recycling department and the chemical department were integrated to form a new circular economy department. The company will use its strong sales channels in the automotive industry and its understanding of chemical laws and regulations in various countries to support the development of PCR products that can be used in the automotive industry, comply with chemical laws and regulations when importing and exporting, and expand sales in China and overseas. As an important layout of Haier Smart Home in the recycling field, Haier Recycling relies on the advantages of Haier Smart Home's marketing network, service network, logistics network, recycling network, and channel network. The network innovates the "five-network integration" recycling model and establishes a nationwide network of waste home appliance recycling contacts, which can ensure high-quality, large-scale and traceable supply of waste plastics from home appliances. At the same time, Haier Recycling has laid out the industry's first home appliance recycling interconnected factory, which controls product quality from the entire process of disassembly, cleaning, granulation, etc., and has the ability to develop and stably supply high-quality PCR products, which will promote the green development of the entire industrial chain of the automotive industry. For a high-quality PCR supply chain, a complete recycling system and leading scientific and technological strength are indispensable. In addition to building the country's largest waste home appliance recycling network system, Haier Smart Home Recycling Interconnected Factory has also introduced the industry's most advanced high-quality plastic cleaning and sorting production line and recycling new material production line to achieve circular technology leadership. At present, Haier Smart Home Recycling Interconnected Factory can dismantle 2 million waste home appliances and recycle 30,000 tons of recycled materials each year. Based on the industry-leading recycling technology, the removal rate of metal impurities, glass, copper wire, etc. in the waste plastics disassembled by the factory is 100%, and the impurity rate is less than 0.2%. The purity of the produced recycled new materials reaches 99.9%, and the physical properties are almost 0 attenuation. It can directly replace new materials and be applied to automobile bumpers, interior kits, pedals and other parts, which can not only reduce carbon and cost, but also further improve the reliability and safety of the products. At present, the plastic recycling economy has accelerated into the fast lane of development. Looking to the future, Haier Smart Home will continue to expand its recycling industry layout, expand the application of new recycled materials in home appliances, automobiles and other fields, and export replicable and popularizable experiences and results to contribute to the realization of a circular society.
