Polyurethane Sandwich Panel

Description

PU Polyurethane Sandwich Panel Rigid Polyurethane foam has relatively good heat-resistance, it doesn&#**9;t have obvious change in volume and strength. Its heat condustion rate is relatively small, when density is 0.*3kg/m3 its heat conduction rate is *3j/(m. H. K)(*5cal/m. H. K). Polyurethane and the rock wool sandwich panel are made with double fire-proofing coating steel boards, in the middle, it filled with inflaming-retading material polyurethane or rock wool. It is widely used in the plants, refrigeration storages, stadiums, warehouses, exhibihition halls, amusement parks and etc. Now it has been a newly-typed environmental material in *1st century. Main Characters: 1. Light, brand new, eye-catching, the weight of Polyurethane is on the average of *0kg/m to *4kg/m, equals to the 1/*0 of the red brick, and no need of the refinery in the facade. The weight of the rock wool is on the average of *3kg/m to 1kg/m. 2. With the characters of good intensity, stability, tensity-resistant, and antiknock. In addition, with decayed-resistant, it could be used in fencing structure, and the average housing would not use beam column; 3. With good Heat-preserving, heat and sound insulating, and the condensation-proofing. The Polyurethane with the thickness of *5mm is equals to the red brick with the thickness of ***0mm. 4. With a high degree of Pre-installation, the project period would shorten more than *0 %traditionally. 5. The outstanding character of rock wool sandwich panel is non-combustion material, with good fire-durabilty, and could satisfy every degrees of setting on fire.
