Basalt fiber

Basalt Fiber: Continuous fibers drawn from natural basalt. These fibers are produced by melting basalt at temperatures between 1450°C and 1500°C and then rapidly drawing them through a platinum-rhodium alloy wire-drawing die. Pure basalt fiber is typically brown in color. Basalt fiber is a new type of inorganic, environmentally friendly, high-performance fiber material, composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide. Basalt continuous fibers are not only highly strong but also possess excellent properties such as electrical insulation, corrosion resistance, and high-temperature resistance. Moreover, the production process of basalt fiber ensures minimal waste generation, low environmental pollution, and the ability of the product to degrade directly in the environment without any harm, making it a genuinely green and eco-friendly material. China has listed basalt fiber as one of the four key fibers for development (carbon fiber, aramid, ultra-high molecular weight polyethylene, and basalt fiber), achieving industrial-scale production. Basalt continuous fibers have found wide applications in various fields, including fiber-reinforced composites, friction materials, shipbuilding materials, thermal insulation materials, the automotive industry, high-temperature filtration fabrics, and protective applications.
