| 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.
