PU sandwich panel polyurethane foam sandwich panel mainly consists of three parts:hot galvalumed steel sheet(or aluminum sheet)treated with special fabrication processing on the surface,rigid polyurethane as insulating layer on the medium layer and aluminized paper or glass fabric applied at inner layer.
Advantage of PU sandwich panel for freezer cold room
1. Excellent in thermal insulation
2. High compression resistance performance
3. Good waterproof performance
Good in waterproof, damp proof, and penetration proof. The volume water absorption is less than 1% and steam coefficient is less than 3ng/pa.m.s. , it is much better than other panel.
4. Stable performance and long service life
Thermal insulation performance of XPS panel varies little with time.
Even served more than 50 years, its performance can remain over 80%.
