XPS board is based on polystyrene supplemented by heating a mixture of polymers in the same time, into the catalyst, then the continuity of extruded closed-cell foam extrusion of rigid foam board, independent of its internal closed bubble structure, is a species with a high compressive strength, low water absorption, moisture-proof, airtight, light weight, corrosion resistance, super anti-aging (aging almost no long-term use), low thermal conductivity, excellent performance of environmentally friendly insulation materials. 
 XPS board is widely used in dry wall insulation, flat concrete roof and steel roof insulation, low temperature storage on the ground, parking platform, airport runways, highways and other areas of the moisture-proof insulation, control of ground frost, which is the reasonable price construction inexpensive, quality superb insulation, moisture-proof material. 
 Excellent, long-lasting thermal insulation of 
 As a lower thermal conductivity is the goal of all insulation materials. XPS board mainly made of polystyrene as raw material, while polystyrene is an excellent low thermal conductivity of the original material, supplemented by extrusion extrusion, the honeycomb structure is even more closely and effectively prevent the thermal conductivity, XPS board thermal conductivity 0.028/mk, with high thermal resistance and low linear expansion characteristics. Thermal conductivity is much lower than other insulation materials. Such as the EPS board, polyurethane foam, insulation mortar, perlite, etc. 
 Insulation materials used not only to consider the level of thermal conductivity, but also to achieve the same measure of thermal resistance in insulation materials when different weight ratio. The thicker the insulation the more inconvenient construction, bulk density, the greater the increase in the load structure, so that indirectly led to increased costs. JJLXPS plate light, low-cost combined with a stable chemical structure and physical structure, to ensure that the insulation properties of materials, durable and stable, so the XPS board is the world's one of the best building materials.
