Product Description: XPS foamed board, also named as polystyrene extrusion plastic board (XPS for short) has a perfect closed-cell structure. Its density, water absorption, coefficient of heat conducting and the coefficient of steam pervasion are all lower than those of other heat insulation materials and they are characterized by strong intensity, light material, airtight, anticorrosion, aging resistance, low cost.
It has been widely used for heat preservation, and insulation in the construction industry, frost resistance of the highway, railway, airport, square and household fitment. It is the generally acknowledged as the best heat preservation material at present
