Description RONGSHENG calcium silicate insulation board is manufactured form xonotlite and reinforced fiber. It is entirely asbestos-free and non-poisonous to human body. calcium silicate insulation board is a kind of high efficiency and energy-saving product, with the maximum heat-resistant temperature up to 1000 ℃ . RONGSHENG calcium silicate insulation board has characteristics such as excellent thermal stability, corrosion resistance and convenient construction, can be widely used in industrial furnace insulation. Features  1. Moisture-proof, fire-resistant and corrosion-resistant 2. Good elasticity, high tensile strength and low shrinkage 3. Low thermal conductivity, low heat storage and long service life 4. Light weight, machinable and sound insulation     
Application Calcium silicate board for thermal insulation is widely used in thermal insulation, fire and sound insulation of equipment pipelines, walls and roofs in the fields of electric power, metallurgy, petrochemical, construction, and ships. Calcium silicate board for decoration is used for indoor partition and ceiling of buildings.It is a new type of building and industrial plate with excellent performance.
