PET Foam Sandwich Panel
FRP skin PET foam sandwich panel is a new type of environmentally friendly composite panel, which is made of glass fiber reinforced plastic sheets (mixed with high-quality thermosetting resin and strong short glass fibers) and lightweight rigid foamed PET (polyester) as the core material, lightweight and high-strength. This kind of panel is widely used in RVs, dry truck bodies, building wall panels and other fields due to its excellent heat insulation, corrosion resistance, easy processing and other advantages.
