Calcium Silicate Block
ASK Calcium Silicate Block CS220 is an insulation material molded by reacting calcium silicate powder with high-pressure heat, and mixing it with inorganic fiber. It is a non-asbestos, high performance insulating material designed to provide excellent thermal insulation and heat resistance for piping and equipment in power station, steel mill and petrochemical industries as well as other various fields. It can also be specified to use in furnace as backing material of refractory bricks.
