Product Detail
Polyurethane Hard Foamed Plastic, foam plastic
It has high rate of closed cells and low water absorption
low thermal conductivity, high strength
Rigid polyurethane foam plastic is a new kind of heat insulating material in low temperature. It is mainly made of polyether or polyester plus polyisocyanate ester added with flame retardant, stabilizing agent and foaming agent and it changes into foaming body through chemical reaction after mixed and stirred. It has high rate of closed cells and low water absorption.
Because of the foaming agent air with low thermal conductivity in its cells, the rigid polyurethane foam plastic could self-extinguish. As a result, it is usually used in cold insulation and heat preservation in low temperature condition. It has following features: low thermal conductivity, high strength, light weight, quakeproof, insulation, strong floatability, stable chemical properties and convenience in construction. Consequently, it is widely used in industries of petroleum, chemical engineering, ethylene, refrigerated warehouse, food storage, partition wall and wallboard in family refrigerator and architecture industry. It can be made into the form of slab or pipe by factories for prefabrication or be foamed by sprayed or impregnated on site.
Foam Plastic is good product for insulations.
