Rigid polyurethane foam is a new kind of thermal insulating material for low temperature applications.It is mainly
made from polyether or polyester plus isocyanate 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 will
self-extinguish. As a result, it is usually used to be cold insulation for low temperatures. 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 prefabricated into slab or pipe, or be foamed on site.
