Light weight fire resistant 650 thermal insulation calcium silicate board

Product Overview

Description

Light weight fire resistant 650 thermal insulation calcium silicate board

 

 

650 calcium silicate board is a new type of micro-porous structure rigid insulation materials, uses silicon oxide, calcium oxide, and the reinforcing fibers as its main raw materials, made through mixing, heating, gelling, molding, autoclaving and drying processes. It is known as the stability in different temperature, asbestos-free and high thermal insulation properties at 650C.

 

650 calcium silicate board Characteristics:

1.    Super light weight

2.    Low thermal conductivity,

3.    High rupture and compressive strength,

4.    Waterproof

5.    High insulating effect

6.    High efficiency

7.    Asbestos free

 

650 calcium silicate board Application:

It is widely used in power plants, petrochemical plants, pipeline systems equipment, as well as heating pipe network system and non-corrosive to stainless steel.
