Basalt fiber is a continuous fiber produced by melting basalt rock materials at a temperature range of 1450℃ - 1500℃, and then being rapidly drawn through a platinum-rhodium alloy drawing plate. The basalt winding tape is made by weaving high-quality basalt continuous fibers after processing and surface treatment. This product has characteristics such as high temperature resistance, corrosion resistance, sound absorption and insulation, heat preservation, and radiation resistance. It is widely used in fields such as aviation, military industry, high-speed rail, and automobiles. Continuous working temperature: 700℃
