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%.

5. Environment-friendly

No harmful substance volatile, no decomposition or no mold but anti-corrosive.

The solid waste of XPS can be recycle, which makes it environment-friendly.

We can produce as the client's demand.

2. Good Quality:

We have strict quality control system.Good reputation from home and abroad.
