China Heat Preservation Firepoof Calcium Silicate Board

Heat preservation and firepoof calcium silicate board
Description

1000C porous Calcium silicate board is an asbestos-free excellent thermal insulation product that can withstand continuous 1000ºC operating temperature, which was made from xonotlite by thermoplastic reaction, then mixed with inorganic glass fiber to reinforce the strength. It is also a hydrophobic energy saving product widely used in industrial insulation field.

Standard size: 600x300mm, 610 x300mm, 1000*500mm, 1000*600mm

Thickness: 25 - 100 mm

Temperature limitation: 1000ºC.
Density: 200- 300kg/m3

We can also make special dimensions as customer request.

Features and advantage

Super light weight,Lower thermal conductivity compared with other massive hard refractory insulation materials.High rupture and compressive strengths Easy to install, Reliable and durable.Heat resistance and Non-deformation within the working temperature range Non-corrosiveness to piping and equipmentLong service lifeAsbestos freeWaterproof

Application

Calcium Silicate Board was mainly used as insulation for thermal equipment and piping in the power, chemical metallurgy, petrochemical, textile and light industries as well as insulation for buildings, industrial furnaces and deck of ship
