Your position: Home > Product > 1050 Calcium Silicate

HCS20 Laizhou asbestos free high temperature and high temperature calcium silica
Describe：

Kaifa Calcium Silicate Board

Calcium silicate is mainly made by silicon dioxide and calcium oxide powder with wood fiber as reinforcing material.

It is a new environment-friendly insulation material, non-toxic and no poisonous substance such as asbestos, sulfur and chlorine.

There're 2 types, ordinary microporous calcium silicate of 650°C resistant and high end refractory calcium silicate of 1050°C resistant. 

Features:

Low Thermal Conductivity

Light Bulk Weight

High Compressive Strength

Easy Cutting

Non-Toxic

Water Proof

Long Service Life

Application: metallurgy, petroleum, chemical, electricity, light industry, machinery and other industries insulation; cement, glass, ceramics and other kiln insulation; buildings, vessels and trains insulation; heating power pipes, boiler body insulation and road insulation
