PIR Polyisocyanate foam is a foaming material made by isocyanate after catalysis effect, and its physical and fire prevention properties are better than that of the general PU. It is an ideal organic low temperature heat insulation material, and has the advantages of low coefficient of heat conductivity, light shock prevention, strong adaptability. It can be widely applied in refinery, chemical plant, ethylene, fertile, freezer, refrigerator and building heat preservation and insulation.
1. Good heat conductivity,better than all other insulating materials;
2. Property of fire fighting is up to GB8624.Flame retardancy is B1 Degree and up to ASTM E 84;
3.It has features such as high crushing resistance,low coefficient of heat conductivity and good dimeision stability;
4. It can meet the design requirements for multi-layer structure of varies thickness after being prafiled and so as to ensure the quality of construction;
5.Working temperature can be -196°C-+130°C
