Basalt fibers are continuous fibers made by high-speed drawing of platinum-rhodium alloy wire-drawing leak plate after basalt material is melted at 1450 ~1500 ℃. Similar to glass fibers, its properties are between high-strength S glass fibers and alkali-free E glass fibers. Pure natural basalt fibers are generally brown in color, and some are golden in color.
