What is PU Foam

PU foam, short for Polyurethane Foam, is a porous material formed by the chemical reaction of polyurethane prepolymer with various additives such as blowing agents, catalysts, and flame retardants. Its unique molecular structure endows PU foam with excellent physical and chemical properties, such as good elasticity, thermal insulation, sound insulation, chemical corrosion resistance, and flame retardancy. Therefore, it is widely used in construction, transportation, home appliances, packaging, and many other fields.
