XPS insulation boardIs extruded polystyrene insulation board, it is made from polystyrene resin as raw material and other raw materials and polymer content, through a special process heating mixed with catalyst, rigid foam board and continuous extrusion, extrusion molding and manufacturing. Its scientific name is insulatedwithExtruded polystyrene foam(XPS), XPS has a closed cell cellular structure perfect, this structure allows XPS plate has a rather low water absorption (almost no water), moisture-proof, breathable, lightweight, corrosion resistance, low thermal conductivity, high compressive strength, ageing resistance (normal use almost no aging phenomenon, the use of energy saving and environmental protection decomposition) long service life, low thermal conductivity excellent performance of thermal insulation materials.

The mechanical properties of EPS can not be compared, in addition, due to the continuous extrusion of the tight closed cell structure. Its density, water absorption, thermal conductivity and steam permeability are lower than other types of plates, is currently recognized as the best marketThermal insulation material
