What is polyurethane resin?

A polyurethane resin (commonly abbreviated as PU) refers to a class of polymers comprising a characteristic  of a carbamate in the main chain.

This polymer material is widely used in industrial applications such as adhesives, coatings, low speed tires, gaskets and automotive mats. In the daily life, polyurethane is used to make different foams and plastic sponges. Polyurethanes are also used in the manufacture of condoms as well as medical equipment and materials. Because polyurethane has a very low thermal conductivity.

Therefore, the new wall insulation materials based on polyurethane materials are new wall materials developed in Western countries such as Europe and the United States. In China, wall insulation materials are being promoted, so China's development market has great potential.
