Common: PU (Polyurethane foam)
Polyurethane foam insulation is an ideal kind of organic low temperature heat insulation material. Its thermal conductivity is very little, with light weight and shockproof. It can be made into prefabrications and also can be made cast-in-place. It can be used in oil refining, chemical industry, chemical fertilizer, cold storage, etc. Our materials meet ASTM C591. We can supply Polyurethane foam board, pipe section, or them with kraft aluminium multilayer complex, or with others. No CFC's or HFC C141-b shall be used in the production of PU foam materials.
