1100℃ Calcium Silicate Insulation Board

1.1100℃ Calcium silicate insulation board is formed by press,using silica fume(microsilica),quartz and lime as raw material,synthesized through dynamic hydrothermal process,reinforced with glass fibre and paper fibre.
2.Amorphous silica fill up interspace between xonotlite crystal,it heighten fire-resistance temperature,mainly for back-up insulation of industrial kiln furnace.
