Our company produces polystyrene foam sandwich panel (EPS), extruded polystyrene foam sandwich panel (XPS), polyurethane sandwich panel (PU) for long-term

    EPS sandwich panel production process adopts the colored steel plate as surface board, and the core material is the self-extinguishing closed cell polystyrene foam, It is a kind of high-strength composited building materials, and it was formed in the automated continuous molding machine, by combining the pressed colored steel with the High Strength Adhesives. It has the characteristics of complete insulation and fire-proof, fast construction speed, durability, and beautiful appearance, etc.

    XPS sandwich panel's core material is polystyrene foam, which is formed by extrusion molding. After composited with the colored steel sheet, it has the characteristic as follows:

Low water absorption, high hardness, good anti-corrosion, good thermal insulated capacity, and easy cutting, as well as long life-used, etc.

    PU sandwich panel is formed according to the physical characteristics and unique formula of polyurethane foam, by high-temperature combined together with the colored steel plate in high temperate,the Semi-rigid colored steel sheet is combined with softening chemicals material, The polyurethane foam molding machine can produce the sandwich panel with the characteristic of  low thermal conductivity, temperature range, high compressive strength, water & air tightness, fire-retardant and so on. It is a king of Ideal environmental protection building materials

The above sandwich panels have been widely used in warehouses, factories, exhibition hall, prefabricated house, container houses and other industrial and civil buildings
