"Basalt fiber is a continuous fiber made by melting basalt at 1450℃~1500℃ and then drawing it through a platinum-rhodium alloy drawing plate at high speed. Similar to glass fiber, its performance is between high-strength S glass fiber and alkali-free E glass fiber. The color of pure natural basalt fiber is generally brown, and some are golden. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is made of basalt stone composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, iron oxide and titanium dioxide after being melted at high temperature and then quickly drawn through a drawing plate. Basalt continuous fiber not only has good stability, but also has many excellent properties such as electrical insulation, corrosion resistance, combustion resistance, and high temperature resistance."
