High strength rock wool board

With high mechanical strength, the high-strength mineral wool broad is suitable for exterior thermal insulation of building roof and exterior wall, the production of color-steel sandwich board and other occasions where high mechanical strength is required. The density of high-strength mineral wool board: > 120kg/m3 Compressive strength: ≥ 40KPa(with 10% deformation) Delamination strength: ≥ 7.5KPa Product properties Properties Value Average fiber diameter, um ≤7.0 Organic matter content, % ≤4.0 Shot content (>0.25mm), % ≤12.0 Compressive strength ≥40kPa (with 10% deformation Incombustible Class A Temperature for shrinkage under hot load, °C ≥600 Coefficient of thermal conductivity W/m.K (Average test temperature is 70±5°C) <0.044
