Rock wool board is an inorganic fiberboard made primarily from natural basalt or other rocks through high-temperature melting and fiberization. It typically appears in board form and can be processed into products of different densities and thicknesses depending on the application.
Rock wool board belongs to the category of inorganic non-metallic materials and is characterized by its lightweight, porous nature, high temperature resistance, and strong chemical stability. Its main components include silicon dioxide (SiO₂), aluminum oxide (Al₂O₃), and calcium oxide (CaO), which give rock wool board its unique physical and chemical properties.
The manufacturing process of rock wool board originates from the processing of natural rocks; therefore, it is considered an environmentally friendly material that meets the requirements of sustainable development. Rock wool board is widely used in building exterior wall insulation, industrial equipment insulation, and ship cabin fireproofing.
