China Basalt Fiber Yarn for Heat Insulation Pricelist, Suppliers

Basalt fiber yarn is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to carbon fiber and fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce products such as camera tripods.
Continuous basalt textile yarn is made of multiple basalt strands by primary twisting (usually the filament diameter is under 9Î¼m).
Continuous basalt textile yarns can be divided into weaving yarns and industrial yarns, and weaving yarns are usually made into cylindrical or milk bottle shape packages.
