The basalt casing is made of woven continuous basalt fibers. It generally requires processing and surface treatment before use. Due to its excellent electrical insulation properties, high-temperature resistance, and chemical corrosion resistance, it is suitable for insulation tubes in electrical appliances and motor coil areas. It can also be used as insulation tubes for internal connection wires and various high-temperature joints. Additionally, it can serve as a substrate for patterned tubes, brush hoses, and high-temperature composite pipes, and can replace carbon fiber casings for medical correction and repair procedures.
