1. Good air tightness
Concave and convex groove structure,
improve the insulation and air tightnessof the joint of the plate, effectively solvethe temperature difference of therefrigerated industry, specially designedfor the cold room and warehouse.

2. Thermal insulation
Polyurethane material porositystructure is stable, basically closed cellstructure, not only good thermalinsulation performance, but alsofreeze-thaw resistance, soundabsorption is good.

3. Fire and Flame retardant
The polyurethane material is added with flame retardant in the
foaming process, and the formed polyurethane material is flame
resistant and self-extinguishing, and carbon deposits are formedon the foam surface during combustion, effectively preventingthe spread offire.

4. Beautiful facade
The surface of the polyurethanecold storage board is automaticallycoated, and the fully automatedassembly line is formed once toensure the cleanliness and beautyof the board.
