Non-asbestos high density calcium silicate board produced using Dynamic Method thin-fiber xonotlite (CaO·SiO₂·H₂O). Very high strength, nearly no thermal shrinkage, excellent resistance to thermal shock. Widely used for machine parts, moulds and demanding industrial insulation.
The main high-density calcium silicate materials on the market are made of xonotlite with molecular structure CaO·SiO₂·5H₂O. Our factory uses a Dynamic Method to produce thin-fiber xonotlite with the structure CaO·SiO₂·H₂O.
The newly invented material has lower thermal conductivity, higher service temperature, and is durable for a longer service life compared to conventional high-density calcium silicate products.
Widely used in different industries, formed into various shapes as machine parts or moulds for demanding high-temperature applications.
Standart Boyut: 1230 × 1230 mm thickness 6-160mm; 1250 × 2500 mm thickness 10-80mm; 1200 × 600 mm thickness 10–160 mm (custom sizes and shaped products available)
