XPS foamed board extruder, the final product name as XPS for short:With standard closed-pore alveolatestructure, its density, water absorption, coefficient of heat conducting and the coefficient of steam pervasion are all lower than those of other board heat preservations materials. Because the characteristics

of low cost, airtight, strong density, light material, anticorrosion and aging

resistance, it's widely used in the heat resistance of the highway, railway,

airport, heat preservation and heat insulation in the construction industry. It's

acknowledged of the best heat preservation material in this present market.
