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,1000C.
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.
PRODUCT FEATURES
