Product Description

Pu sandwich panel, which structure is FRP skin + core material + FRP skin.

FRP sandwich panel are composed of Gel coated FRP skins on both sides of a PU foam (Polyurethane) core. Regular FRP skin thickness is 1.5mm, 2.0mm and 2.5mm. Total Panels thickness frequently used is 25mm, 30mm, and 50mm. Panel size can be customized as per customers request.

FRP sandwich panel are a high-tech, high-quality new sheet, it does not occur in the ultra-low temperature of 40 degrees brittle crack, high temperature below 100 degrees will not be deformed, and can prevent heat transfer.

FRP sandwich panel can replace color steel plate, aluminum, etc., And to overcome the traditional products rust, corrosion, easy to depression deformation, can not adapt to harsh environments and other shortcomings.

FRP sandwich panel with gel coated, can be self-cleaning, anti-uv, anti-static, etc, is the most popular international truck body and van panel.
