Better durability. Low thermal conductivity. Light weight and high specific strength. Long service life. Better applicatio
The main constituents of calcium silicate products are Xonotlite and reinforced fibre, no asbestos. It is a kind of high efficient energy-saving material with temperature limited 1100 cent-degree. They are recommended as thermal insulations of piping and equipment in heat supply network of city construction, metallurgy, petroleum, chemical, electronics, machinery, glass as well as other various fields. It can also be specified to use in furnace as backing material of refractory bricks.
Product Performance Characteristics
Better durability. It can withstand continuous heat load within the temperature limits.
Low thermal conductivity. It has the incomparable insulation performance within the application range.
Light weight and high specific strength. Its specific strength is the highest among the rigid insulation materials.
Long service life. It will not produce the powder after long periods of operation as the ceramic fiber felt will do.
Better application adaptability. It can be Free Cutting by ordinary woodworking tools.
Safe and clean. It has not toxic materials such as asbestos sulfur and chlorine.
Not afraid of wetted. Its performance remain unchanged after being dried.
