XPS foam sandwich panel is a kind of thermoplastic composite panel containing thermoplastic resin and continuous fiberglass. The outer skin adopts glossy continuous glass fiber and the inner skin is composited with thermoplastic UD tapes. The core adopting extruded polystyrene connects with the skins through vacuum compression with special adhesives.
The outer skin with glass fiber is formed by an automatic panel line. The surface is coated with a colorful gel made of international food-grade resin. The gel coat makes the panel surface more smooth and easy to clean. The panel becomes colorful and glossy. The panel is brightly colored and glosses retained.
The high body strength of extruded polystyrene in the core prevents the damages caused by embedded parts and gives the panel a flat appearance without indentations. The extruded polystyrene also performs well under the temperature as low as -50℃.
The continuous fiber-reinforced thermoplastic UD tapes used in the inner skin of the panel are laminated in different directions, thus keeps the fiber continuity and reinforces the material in every force direction. This part is lightweight and strong in specific strength and specific modulus. It is water, corrosion, impact, and rubber resistant, and inert to most acids and alkalis. The inner skin is formed with thermoplastic PP, which is recyclable with no gas polluting.
