The Main Applications of Rock Wool

Rock wool is based on basalt as an important material, after melting at high temperature, made of artificial inorganic fiber by high-speed centrifugal equipment, at the same time adding special binder and dustproof oil, and then curing by heating, made into various specifications, different requirements of rock wool insulation products. Rock wool, mineral wool can be made into rock wool board, rock cotton, rock wool felt, rock wool blanket (rock wool felt), rock wool pipe and other rock wool products.

Overview

The main application rock wool in the industrial field:
