XPS heat preservation board is a kind of extruded polystyrene heat insulation board. It is made of polystyrene resin as raw material, with other raw materials and accessories and poly-inclusions, through a special process of heating, mixing and injecting catalyst, and then continuous extrusion and extrusion molding of rigid foam plastic board. Its scientific name is extruded polystyrene for insulation. Foam plastic (XPS), XPS has a perfect closed-cell honeycomb structure, this structure makes XPS board has very low water absorption (almost no water absorption), moisture-proof, air-tight, light weight, corrosion resistance, low thermal conductivity, high compression resistance, aging resistance (normal use almost no aging decomposition), long service life, low thermal conductivity. Energy saving and environment-friendly insulation materials with excellent performance.
Its mechanical properties are incomparable with EPS, in addition, due to continuous extrusion due to the tight closed-cell structure. Its density, water absorption, thermal conductivity and steam permeability are lower than other types of plate, is currently recognized as the best insulation material.
