Hidden champion in the cryogenic field: How PIR insulation materials become a new name card for Made in China

In the liquefied natural gas storage and transportation environment of minus 196℃, a foam material called polyisocyanurate (PIR) is quietly guarding the country's energy security. With an ultra-high closed-cell rate of more than 90%, this modified polyurethane material has shown irreplaceable ...

The Silent Revolution of PIR Materials: Performance Breakthroughs and Circular Practices in Building Energy Saving

In the field of industrial insulation, polyisocyanurate (PIR) foam is reshaping industry standards with disruptive performance. Its closed-cell rate exceeds 90%, and its thermal conductivity is as low as 0.022W/(m·K), which is 30% more energy-saving than traditional polyurethane, and its fire ...

PIR materials: invisible innovators in the field of building energy conservation

In the field of industrial insulation, polyisocyanurate (PIR) foam is rewriting the rules with disruptive performance. Its closed-cell rate exceeds 90%, and its thermal conductivity is as low as 0.018W/(m·K), which is 30% higher than that of traditional polyurethane insulation, and its fire ...

PIR engineering plastics: A circular revolution from factory waste to high-end applications

In electronic manufacturing workshops, the scraps squeezed out of injection molding machine nozzles were once considered waste, but now they have become treasure raw materials for high-end engineering plastics - this is the value leap of PIR (pre-consumer recycled) materials. Unlike PCR plastics ...

Acer laptop computer "sprinkle design" solves the problem of PCR material appearance, and the electronics industry has set off a spray-free revolution

Consumer electronics brands are actively implementing environmental protection commitments. Lenovo, Acer, and Dell all plan to achieve a 30%-100% recycled plastic ratio in their products between 2025 and 2035. However, PCR materials have long restricted the appearance design of high-end electronic ...
