Basalt Fiber: Continuous fibers drawn from natural basalt. These fibers are produced by melting basalt at temperatures ranging from 1450℃ to 1500℃ and then rapidly drawing them through a platinum-rhodium alloy sieve. Pure basalt fiber typically has 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 offer high strength and possess multiple excellent properties, including electrical insulation, corrosion resistance, and high-temperature tolerance. Moreover, the production process of basalt fiber ensures minimal waste generation, low environmental pollution, and the ability to degrade directly in the environment post-use, 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 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.
