The main function of polyurethane foam produced by polyurethane foaming agent is buffering. Polyurethane soft foam is often used for sofa furniture, pillows, cushions, toys, clothing and soundproof lining.

Polyurethane foaming agent of polyurethane rigid body is a kind of heat preservation and waterproof function of new synthetic material, its coefficient of thermal conductivity is low, only 0.022 ~ 0.033 W/(m * Κ), equivalent to half of the extruded board, it is the lowest all heat preservation material coefficient of thermal conductivity. Rigid polyurethane foam is mainly used in building external wall insulation, roof waterproof insulation integration, cold storage insulation, pipe insulation materials, building boards, refrigerated vehicles and cold storage insulation materials.
