Polyurethane (PUR) is a new type of low-temperature thermal
insulation material. It is formed by mixing and stirring the main
raw materials of polyether or polyester and polyisocyanate and the
auxiliary materials of flame retardants, stabilizers and foaming
agents. Due to the foaming agent gas with low thermal conductivity
in its pores, it has certain self extinguishing property, and is
often used for heat preservation in cold and low temperature range.
Due to the advantages of small thermal conductivity, high strength,
light weight, sound insulation, shockproof, insulation, strong
floatability, stable chemical performance, and convenient
construction, it is widely used in petroleum, chemical industry,
ethylene, cold storage, food storage, household appliance
refrigerator, partition wall and wall board in the construction
industry. When used, it can be prefabricated into plate or shel in
our plant, and can also be sprayed or poured with foam on site.
