1100C CALCIUM SILICATE INSULATION BOARD

1100C  CALCIUM SILICATE INSULATION BOARD
   Using silica fume(microsilica) ,quartz and lime as raw material, synthesized through dynamic hydrothermal process, reinforced with glass fibre and paper fibre , ca-si-board is formed by press.Amorphous silica fill up interspace between Xonotlite crystal ,it heighten fire-resistance temperature, mainly for back-up insulation of all refractory xonstructions.
