New Material-Basalt Fiber as an Alternative for Glass Fiber
【Characteristics】
(BST) Basalt fiber is a continuous fiber made of basalt stone material after melting at a temperature of 1450-1500 degrees, drawn by a platinum-rhodium alloy and stretched at high speed. Like glass fiber, its properties are between high-strength glass fiber and alkali-free glass fiber. Between the fibers, natural basalt fiber has a brown color and a goldish color. Basalt fiber is a new type of inorganic environmentally friendly high-performance fiber material, which is a basalt stone composed of oxides such as silicon dioxide, alumina, calcium oxide, iron oxide and titanium dioxide. It is made by quickly passing through the drain plate after melting at high temperature. Basalt fiber not only has good stability, but also has many excellent properties such as electrical insulation, corrosion resistance, resistance to burning and resistance to high temperatures, etc.
