Basalt Fiber: Continuous fibers drawn from natural basalt. These fibers are produced by melting basalt material at temperatures ranging from 1450℃ to 1500℃ and then rapidly drawing them through a platinum-rhodium alloy wire-drawing die. Pure basalt fibers typically have a brown 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 high in strength 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 biodegrade directly in the environment without any harm, making it a truly 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 production. Basalt continuous fibers have been widely applied in various fields, including fiber-reinforced composites, friction materials, shipbuilding materials, thermal insulation materials, the automotive industry, high-temperature filter fabrics, and protective applications.
