Extrusion polystyrene board(XPS board):

Extrusion and expanded polystyrene(XPS) thermal insulation boards are made in polystyrene. Through special process, the hard expanded board is extruded. There is a sealed and foamed structure, which is an environmental protection material with the performances of high-resist compression, waterproof, moistureproof, air proof, light weight, anti-corrosion, long service life and low conductivity factor and so on.

Superior performance make it fit for a wide range of acoustic and thermal insulating
applications, including roofing, wall, freezing plant, refrigerator car, roof parking, roof tennis court, roof garden, platform and ground underlong-time load, expressways, rail bed and household fitment. XPS foam board can also be laminated with film or paper for education materials, decorating objects, advertising board.
