Vermiculitplatte

Vermiculite board is a non-combustible board in which the unique cellular structure of vermiculite is maintained and controlled by a pre-treatment process. This gives excellent thermal insulation properties with dimensional stability at high temperatures. It is used extensively for the fire protection of structural steel elements in buildings to provide up to 240 minutes fire protection. It may also be used to protect sheet metal ducts and for the construction of smoke extract ducts. Available in two grades: @ Thicknesses from 20mm to 40mm suitable for up to 180minutes fire resistance@ Thicknesses from 45mm to 80mm suitable for up to 240minutes fire resistance Typical Vermiculite Board(VICUBO-700) SpecificationVICUBO(700)Maximum service temperature1100Bulk Density,dryKG/M3700Cold crushing strengthMpa2.2Modulus of ruptureMpa1.8Loss of ignition%6.61Linear reheat shinkage12h # 900 degree celsius%<2.55Thermal conductivityMean temp.@200W/(mxK)0.135@400W/(mxK)0.173@600W/(mxK)0.182@800W/(mxK)0.198Standard size and thicknessThickness30,35,40,45,50,55,60mmLength and width2100x900mm & 1000x610mmOther sizes are available upon requestChemical AnalysisSiO2: 53.39%Al2O3: 11.22%Fe2O3: 3.41%TiO2: 0.73%CaO:1.53%MgO: 13.98%K2O:4.05%Na2O: 6.90%
