Product Details

Basalt Fiber Roving

Basalt fiber 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.

Basalt roving is bundle of continuous mono directional complex basalt fibers. Roving possesses high natural strength, resistance to aggressive environments, long service life and excellent electric insulating properties. By its technical characteristics, Basalt roving surpasses S-glass and E-glass by many parameters, and is almost as good as carbon. Basalt roving is extremely heat resistant: long-use temperature range is 200-680°c. Temporarily it can work in up to 900°c. Roving is extremely hard: 8-9 on the Moh scale (for comparison diamond=10). Its specific strength is 2.5 times higher than alloy steel and 1.3 times higher than E-glass.
