Standard Type Calcium Silicate

Calcium silicate is mainly made of 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.


Low Thermal Conductivity
Light Bulk Weight
High Compressive Strength
Easy Cutting
Water Proof
Long Service Life


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.
