Leadsun Calcium silicate products, also called asbestos free mipor calcium silicate products, are mainly used in industries like power, oil, chemical, shipping, metallurgy, light to provide thermal insulation on industrial pipelines and thermal equipment to decrease heat loss, lower cooling effect on medium and delay its condensation during production, meanwhile save energy, improve work efficiency, lower the temperature at work area, improve working condition, avoid scald among workers.
