Polyurethane Sandwich Panel
Polyurethane foam sandwich panel is fit for the projects which have serious require of keeping warm. Polyurethane core material is considered to the best material in keeping warm and thermal insulation.
The Polyurethane block material become steady after it froth, then combining with metal plates. The characteristics of this technique are: the polyurethane froth, after this chemical reaction is stable, we cut the polyurethane into pieces which with different thickness.
The polyurethane sheet material has stable physical performance, it can combine with pre-painted hot galvanized steel sheets or stainless steel sheet, the surface is smooth and the whole performance is excellent.
