Polyurethane Sandwich Panel Features:
1) Light weight: Only 10 - 14kgsm, the installation is convenient and flexible; Not requiring large-scale lifting devices, and thus lowering building costs
2) High intensity and large rigidity ensures suitability for weight-bearing structures and for supporting and protective structures
3) Good temp-keeping and heat insulation: Average thermal conductivity is 0.023w/m. K
4) Fine fireproof: Test by national quality inspection center for fireproof building material, all its index reach grade B1 and grade A of GB8624 respectively
5) Flexible application: As the continuous production line is controlled by the computer system, the length of the said compound sheets will be decided and selected according to the designing requirements, transport and installation conditions
6) Can select different thickness of the composite panels in accordance with the proof load bearing and purlin distance
