| Message: | IntroductionGlass wool board is one category of glass fiber, a kind of man-made inorganic fiber. With quartz sand, limestone and dolomite as main raw material, companying some sodium carbonate and sodium borate will melt into glass. In the state of melting, with external force, it will be spun into cotton shaped fine fiber, with fiber and fiber crossing and twisting together, showing lots of tiny gaps among them, which can be regarded a pore space. So glass wool can be treated as multi-pore material, with an excellent thermal insulation and sound absorption property.Technical IndexThe main physical performance index of Centrifugal glass woolItem boardDensity--kg/m324-96Fiber dimater--μm2-8 Moisture content--%≤1Combustion performance levelNon-combustible A levelThe thermal shrinkage temperature under load--℃≥250Thermal conductivity--W/mk0.038-0.06Hydrophobicity--%≥98.2moisture absorption--%≤5acoustic absorptivity 24kg/m3 2000HZshot content--%≤0.3Service temperature--℃-120~450ApplicationsThermal insulation, cold insulation and sound absorption for roofThermal insulation and cold insulation of buildingsMovie theater, TV station, broadcasting station, laboratory and sound absorption url:http://www.lfinsulation.com |
