WPUR Rigid Polyurethane

WPUR rigid polyurethane is a professional cryogenic insulation material made primarily from polyol and isocyanate, supplemented with flame retardants, foaming agents, and stabilizers. Through mixing and stirring, a chemical reaction produces a foam body. It offers excellent processing performance and can be prefabricated or processed into flat panels or pipe shells. With a high closed-cell rate, low water absorption, low thermal conductivity, and ease of installation, it also has a degree of self-extinguishing property and is widely used for low-temperature insulation.
