PIR (Polyisocyanurate foam)

PIR polyisocyanurate foam

PIR polyisocyanurate is a kind of foaming material made from the reaction of polyether and isocyanate after catalysis reaction.It excels common polyaminoester foaming material in physical behavior and flame resistance.It is an ideal organic low temperature heat insulation material.Its thermal conductivity is very low ,with light weight and shockproofing .It can be made into prefabrications in-site freely according to a client.It is widely used in oil refining ,chemical industry, ethylene production and storage,chemical fertilizer, cold storage and construction industry ,etc. It can be in pipe and slab. Our insulation materials are asbestos free. No chlorofluorocarbon (CFCs) or Hydrochlorofluorocarbon (HCFCs) be used in the production of our insulation. It can be covered aluminium foil, glass fibe cloth or others. It can meet ASTM C 591-17.

1.B1, B2 fire rate

2.Working temperature scope is –196℃~200℃

3.Excellent dimension stability

4.Can be prefabricated freely according to customers requirement
