Our production of glass fiber reinforced plastic (FRP) polyurethane(PU) sandwich panel, inner and outer sides are the FRP plate, clip core layer is polyurethane foam, high-pressure composite made by vacuum technology. Sandwich panels smooth surface, dirt can easily get rid of, the entire panel colorful and has excellent gloss retention. The glass plate surface layer of gel coat with excellent performance, the atmosphere, water, and in general the concentration of acid, alkali, salt, and other media have a good chemical stability; Surface finish high gloss retention, excellent, no discoloration, corrosion-resistant, anti - bright and promising, anti-aging. Can be customized according to the customer: The biggest sandwich panels can be achieved 13.8 meters X3.6 m (length X width), thickness 25mm, 45mm, 55mm, 65mm, 75mm, 105mm, also according to the specifications of size of the system user needs to do.
