Application
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.
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.
