Our premium rock wool products are meticulously crafted from the finest natural rock materials, including basalt and dolomite. Blended with precise amounts of binder, these ingredients undergo high-temperature smelting and are then converted into fibers using high-speed centrifugation through a state-of-the-art four-roller centrifuge. The resulting fibers are collected, folded, solidified, and cut with precision into various sizes. Our finished products boast exceptional non-combustibility, low thermal conductivity, superior sound insulation, and outstanding chemical stability. Ideal for use in exterior walls, metallurgy, electric power, chemical industries, construction, and shipbuilding, our rock wool boards offer cost-effective and highly efficient thermal insulation solutions. The water-repellent variant, with an impressive water-repellent rate exceeding 98%, is free from *** and ***, ensuring no corrosive impact on equipment. Available in a variety of forms, including boards, blankets, sticks, and pipes, our versatile rock wool products meet diverse application needs.
