calcium silicate board

fire resistant calcium silicate boardcalcium silicate boardcalcium silicate insulation board Calcium silicate is commonly used as a safe alternative to asbestos for high temperature insulation materials. Industrial grade piping and equipment insulation is often fabricated from calcium silicate. Its fabrication is a routine part of the curriculum for insulation apprentices. Calcium silicate competes in these realms against rock wool as well as proprietary insulation solids, such as perlite mixture and vermiculite bonded with sodium silicate. Although it is popularly considered an asbestos substitute, early uses of calcium silicate for insulation still made use of asbestos fibersNR Calcium Silicate Board are widely used in high temperature area for thermal insulation. NR is professional supplier of Calcium Silicate Board and other thermal insulation material. We have been in this industry for years and have good networks.
