(1)Introduction：

　　Tianfon Xu panel is a kind of insulation composite panel produced through continuous production line, using hard-foamed polyurethane foaming as the insulation layer, strengthen steel plate as the interface layer. Tianfon Xu panel adopts to various civilian use external wall insulation panel.

　　(2)Tianfon Xu panel specification：

　　(2)Production features：

　　1. Excellent insulation performance, the lightest insulation layer

　　Hard formed polyurethane is at present the thermal insulation material with the lowest thermal conductivity（0.024W/（m.k））, along with the improving energy-saving standards, polyurethane is the most ideal insulation material. To achieve the same insulation effect, with the thinnest insulation layer and smallest dead-load moment, so can improve the safety greatly.

　　2.Good fire retardant performance

　　Hard foamed polyurethane is thermoset insulation material, it forms carbonization coke when meeting fire, so to prevent fire spread. External insulation mostly at construction site, the polyurethane is self-extinguishing material, meanwhile, both sides of this composite panel is inorganic material, it avoids the fire effectively during the construction progress.

　　3.Small service temperature range

　　Hard formed polyurethane service temperature ranges from -50℃ to 150 ℃，service temperature can reach 250℃ in short period without any damage, it is the widest rang of service temperature insulation material, can be applied to all area including severe cold, cold, hot in summer and cold or worm in winter, and high temperature climate.

　　4.Good system matching, quick construction

　　Hard foamed polyurethane composite panel interface material is cement inorganic material, which is the same material as the bond mortar and plastering mortar, it is good matched, so can guarantee safe and reliable engineering system in long time. The adhesive technology of composite panel can reduce wet construction, improves the construction speed.

　　5.Smooth external wall construction effect

　　After the external wall coating, the external wall is smooth because of the xps panel and eps panel.

　　6.Good weather resistance

　　Hard foamed polyurethane has good materialization stability, it has the same long service life as construction building.

　　7.Low water absorption, good water proof

　　Hard foamed polyurethane is closed structure, low water absorption, it is good water proof and insulation production.
