PUR/PIR sandwich panel

Product advantages

• The tongue and groove joint structure improves the insulation and air tightness of the panels and is specially designed for cold storages.

• The panels are uniform and stable and extremely excellent in both heat insulation and waterproofing.

• The panels have light weights and beautiful appearances, solving the temperature difference problem of the cold storage industry effectively.

• Within certain modulus, the cold storages may change freely in length, width and height directions to get bigger or smaller according to actual needs. The knockdown boards may be remounted at another place conveniently and quickly.

PIR Products

Polyisocyanurate is called PIR for short. For the composite boards developed by us, excessive isocyanurate is added and ring structure and higher isocyanurate index are employed in the compounds to form compact PIR products, thus ensuring greater stability and excellent heat and fire resistance for the internal rigid foams. Experiments show that the products can endure a temperature up to 200℃ in short time period or to 160℃ for long time.
