Rock wool products are mainly made of high-quality basalt, dolomite, and other raw materials. After high-temperature melting, they are centrifuged into fibers using a four axis centrifuge at high speed. At the same time, a certain amount of binder, dustproof oil, and water repellent are sprayed into them. After being collected by a fiber collector, they are cured and cut using a pendulum method and three-dimensional fiber laying method, forming rock wool products of different specifications and purposes.

Due to the fact that rock wool products are artificial inorganic fibers processed through high-temperature melting, they have the characteristics of light weight, low thermal conductivity, heat insulation, and flame retardancy, and are widely used in various industries.
