 Expansion of EPS and continuity out of XPS are two, compared with EPS Panel, XPS board is the third generation of rigid foam insulation material from the process to overcome the complexity of the production process of the EPS board, B1 grade extruded plate with EPS The board can not be replaced by superior performance. It is a sheet of polystyrene resins and other additives manufactured by the extrusion process of continuous and uniform surface and obturator-honeycomb structure, honeycomb structure of the slab, the B1 grade extruded board will not void this insulation materials of the closed-cell structure can have different pressures (150-500Kpa) also has the same low thermal conductivity (0.028W/MK) and enduring the excellent insulation and compressive properties, the compressive strength of up to 220-500Kpa. The mechanical properties of EPS can not compare, addition, because the continuity of extrusion due to the close of the closed cell structure. Its density, water absorption, thermal conductivity and steam penetration are lower than other types of plates, is acknowledged as the best insulation materials. XPS insulation board insulation is extruded polystyrene insulation board, B2 extruded plate based on polystyrene resin as raw materials with other raw materials and poly-containing material into the catalyst by heating the mixed and then extruded pressure molding and manufacture of rigid foam board. B2 grade extruded board its scientific name for thermal insulation extruded polystyrene foam (referred to as XPS), XPS, has a perfect closed-cell cellular structure, this structure allows the XPS board extremely low water absorption (almost non-absorbent), low thermal conductivity, high compressive strength, aging resistance (normal use almost the phenomenon of aging of decomposition).
