China Heat Insulated Polyurethane PU Sandwich Cold Room Storage Roof Wall Panel

1. Introduction of PU Sandwich Panels
Polyurethane PU sandwich panel fits for the projects which have strictly requirements of keeping warm or sound absorption. Polyurethane core material is considered to be the best material in keeping warm and thermal insulation. The Polyurethane material become steady after it is foamed, then combining with metal plates.

2. The characteristics of this technique of Frothing
The polyurethane foam panels after this chemical reaction is stable, we cut the polyurethane into pieces which with different thickness according to customers' requirements. 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.
4. Advantages of Polyurethane Sandwich Panel
Heat and sound insulation:
The outer steel sheets can maintain the lastingness of the color of the building,and reduce the solar radiation and keep the appropriate indoor temperature.The high quality heat insulation materials are made with the adoption of polyurethane PU. Polyurethane Sandwich Panels thermal stability is quite good, when the temperature is lower than 120°C,the volume and the intensity have no obvious change,its Thermal conductivity is small,when the density is 0.03kg/m3, the heat conductivity is only 63J(m.h.k)(15cal/m.h.k).

A degree inflaming retarding:
This system can effectively prevent the fire and prevent the fire from spreading during the cross construction and during the use of the boards. A class fire-resistance( 650.C)fire-resistance period(120min)
