Rock Wool products are manufactured with basalt as main ingredient with little bakelite after melting and solidifying. It is incombustible and sound proof, having many other good properties like low thermal conductivity and chemical stability. Therefore they are widely used in various industries, such as chemical, metallurgical, construction, ship building and electric power etc. Rock wool products do not erode the equipments, because they have no FI and Chlorine, which can be really ideal and economic insulation material. We can produce many shapes of rock wool products, including strip, board, blanket, sewed blanket and pipe.
