Rock Wool Tape

Rock wool tape is a new type of fireproof and thermal insulation material made of natural basalt as the main raw material, melted at a high temperature of more than 1600℃, and made by advanced centrifugal fiber-forming process. During the production process, the molten rock wool is formed into fibers by a high-speed rotating centrifuge, and an environmentally friendly binder is added. The fibers are arranged vertically through a special directional laying process, and then precisely pressed and solidified, and finally cut into strip products. This unique vertical fiber structure gives the product significant advantages: its tensile strength can reach more than 80kPa, its compressive strength exceeds 40kPa, and its mechanical properties are more than 50% higher than those of traditional parallel fiber products, which can better withstand various stresses during construction and use.

 

As an A1-level non-combustible material, the rock wool tape can still maintain structural stability at a high temperature of 1000℃, does not burn when exposed to fire, and does not release toxic smoke. Its fireproof performance far exceeds the national standard requirements. It also has excellent thermal insulation performance (thermal conductivity 0.038-0.042W/(m·K)) and good hydrophobicity (hydrophobicity ≥ 98%), which can effectively block heat conduction and prevent water vapor penetration. The product also has excellent sound insulation and corrosion resistance, does not contain asbestos and other harmful substances, and complies with national standards such as GB/T 19686.
