  Traditional ABS plastic materials have already had better physical and chemical properties. For example, the traditional TV material has good light transmission, suitable for the production of plexiglass, its hardness and maneuverability is also relatively high, in the industrial aspects of the use of a wide range. But its environmental adaptability is very poor, generally in the case of minus 35 degrees to minus 130 degrees outside the deformation will occur. And if it is in the case of direct sunlight, it is easy to be affected by ultraviolet rays and produce color changes, or changes in physical properties. Therefore, traditional ABS materials are generally only suitable for indoor use.     After adding special substances, ABS plastic material inherits the excellent performance of traditional ABS plastic material, and has better stability, and some other properties. This is the infrared ray penetrating ABS plastic material we introduced today. First of all, it has a wider range of adaptable temperatures, and can be used between -35 degrees Celsius and 135 degrees Celsius above zero, without being prone to thermal deformation. Infrared penetration, the color can be in the case of outdoor children are not prone to changes in nature. Therefore, its practicality in daily life is also more extensive.

Recycled ABS Grade A refers to the raw materials used for the edge of the material has not landed, or known as the lower corner of the material, some of the water mouth material, rubber head material, etc., the quality is also better, is not used, in the process of processing the new material, the remaining small edges, or the quality of raw materials is not pass. With these as the gross material processed out of the particles, the transparency is better.   Recycled ABS Grade B refers to raw materials have been used once, but except for high-pressure granulation, high-pressure granulation in the use of imported large pieces of the majority of imported large pieces if the industrial film, is not after the wind and the sun, so its quality is also very good, processed out of the particles of good transparency, which should also be based on the brightness of the particles and whether the surface is rough to judge.   Recycled ABS Grade C refers to raw materials have been used two or more times, processed pellets, its elasticity, toughness and other aspects are not very good.   The recycling sources of ABS recycled plastic pellets are mainly divided into scrap recycling, engineering recycling, etc. However, after recycling and secondary processing of recycled plastic pellets, the original mechanics, elasticity and engineering of ABS pellets are reduced to different degrees.

  Plastic ABS resin is the largest and most widely used polymer, which organically unifies the various properties of PB, PAN and PS, and has excellent mechanical properties with balanced toughness, hardness and rigidity. After actual use, it was found that ABS plastic pipes are not resistant to sulfuric acid corrosion, and will be crushed and cracked when exposed to sulfuric acid. Most ABS is non-toxic, impermeable, but slightly permeable to water vapor, low water absorption, room temperature immersion for one year water absorption rate does not exceed 1%, and the physical properties do not change. The surface of ABS resin products can be polished to produce highly glossy products. In addition, ABS is 3-5 times stronger than general plastics. ABS plastic is odorless and has an ivory-colored translucent appearance, or transparent granules or powders. The density is 1.05~1.18g/cm3, the shrinkage is 0.4%~0.9%, the elastic modulus value is 2Gpa, the Poisson's ratio is 0.394, the hygroscopicity is 250℃.   ABS has excellent comprehensive physical and mechanical properties, good low temperature impact resistance, dimensional stability, electrical properties, wear resistance, chemical resistance, dyeing, finished product processing and mechanical processing. ABS resin is resistant to water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, and easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons. ABS resin has low heat deflection temperature, flammability, and poor heat resistance. Its melting temperature is 217~237 °C, and the thermal decomposition temperature is above 250 °C. Many of the modified ABS materials on the market today are doped with nozzle materials and recycled materials. As a result, the performance of the customer's molded products is not very stable.   Ps: The above news come from website.

  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.
