The rigid polyurethane foam insulation material is mainly composed of isocyanate and polyether polyols.

Rigid polyurethane foam insulation material is mainly composed of isocyanate and polyether polyols, and then with a small amount of additives and auxiliary materials. It is automatically solidified by automatic computer equipment. It has excellent heat and cold insulation performance. At present, it has been widely used in construction, cold storage, refrigerated truck, sports facilities, parking lot, refrigerator air-conditioning equipment, petrochemical pipeline, sound-absorbing room, radar aviation communication, mobile house, carbon crystal wall heating board, floor heating, etc., which is the most ideal anti-corrosion and thermal insulation material in the world.
