It's really a high-quality and low price material.
Extrusion and expanded polystyrene (XPS) thermal insulation boards
Extrusion and expanded polystyrene (XPS) thermal insulation boards are made with polystyrene. Through special process, the hard expended board is extruded, which is an environmental protection material with the performances of high-resist compression, waterproof, moisture-proof, air proof, light weight, anti-corrosion, long service life and low conductivity factor and so on.
Extrusion and expanded polystyrene (XPS) thermal insulation boards can widely used as thermal insurance and moisture-proof material for wall, concrete roof, steel-structure roof, lower-temperature storage floor, car platform, air landing strip, high-way and other fields. It can control frost heaving of the ground and really a high-quality and low price material.
