- product introduction:The polyurethane modified polyisocyanurate insulation sandwich panel (PIR) produced by Changzhou Xueyuan is a kind of foam which is fully mixed, reacted and foamed by two-layer metal panel (or other material panel) and isocyanate in polyether directly in the middle of the panel, catalyst, fireproof agent and environment-friendly foaming agent Foam polymer. This high-tech organic polymer material has the advantages of excellent fire resistance, low thermal conductivity, good waterproof property, stable chemical property and good ageing resistance. It is the best choice for adiabatic polymer materials used in cryogenic and percolating temperature environments.
The standards of PIR products conform to the national standards and specifications, including:
1) Code for design of cold storage (GB 50072-2010)
2) JB / t6527-2006 "heat insulation sandwich panel for combined cold storage"
3) Sb / t10797-2012 indoor assembled cold storage
PIR material properties:
1) The fire resistance and flame retardancy meet the requirements of GB 8624 flame retardant grade B1
2) Used in ultra-low temperature environment, it has excellent properties such as strong compression resistance and excellent dimensional stability;
3) Cutting and shaping can meet the design requirements of composite multi-layer mechanism with various thickness to ensure the construction quality;
4) Temperature resistant range (index above 250): + 150 ℃ for long-term continuous use
5) Using fluorine free foam, the whole process of production is green and pollution-free, and the impact on the ozone layer and greenhouse effect is 0
6) Excellent thermal conductivity, the first of all thermal insulation materials (thermal conductivity 0.019w/mk (25 ℃));
7) The ultra-low water absorption (0.9%) ensures the water and air tightness of the cold storage
