The general trend of green and low-carbon, polyurethane rigid foam industry follows the trend

In refrigerators, foam material usually fills the entire box, in order to keep the internal temperature of the refrigerator constant and provide better thermal insulation. The use of lower carbon feedstocks includes two directions, namely the use of blowing agents with lower GWP values and lower carbon foams. Regarding blowing agent substitution, the refrigerator industry has basically completed the elimination of HFC-245fa.

Carbon emission reduction from the entire polyurethane industry chain is crucial for the refrigerator industry to achieve the "dual carbon" goal. Wanhua Chemical proposed polyurethane foam life cycle solution. The relevant person in charge of Wanhua Chemical said: "We recombine waste polyurethane materials at the molecular level by chemical methods, and then generate polyurethane materials through new chemical reactions. The reaction conditions of this technology are relatively mild, and the product can be directly used for foaming, which has great practical value in the field of polyurethane recycling and can significantly improve economic benefits. In addition, this recycling process enables the foam to be reused without downgrading. "

Thermoplastic Polyurethane (TPU) is a type of polymer resin that is known for its flexibility, durability, and versatility. It is a thermoplastic material, which means it can be melted and reprocessed multiple times without losing its original properties.

TPU is commonly used in various industries, including automotive, electronics, footwear, and sportswear. It is often used to make products such as phone cases, cables, hoses, seals, gaskets, and inflatable structures.
