What is Rigid Polyurethane Foam?
Rigid polyurethane foams are primarily used as thermal insulation in refrigerators, building panels or other similar insulating applications. Rigid polyurethane foam cells are closed, restricting air flow and improving thermal efficiency. Rigid polyurethane foam is formed as a reaction product of an elastopor and isocyanate in the presence of catalysts, surfactant, blowing agent and other additives necessary to complete the foaming process.
