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 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 fiber is made from a single material, crushed basalt, from a carefully chosen quarry source.Basalt of high acidity (over 46% silica content) and low iron content is considered desirable for fiber production.Unlike with other composites, such as glass fiber, essentially no materials are added during its production. The basalt is simply washed and then melted.

The manufacture of basalt fiber requires the melting of the crushed and washed basalt rock at about 1,500 °C (2,730 °F). The molten rock is then extruded through small nozzles to produce continuous filaments of basalt fiber.

And Basalt Fiber Products includes many styles, such as Basalt Fiber Fabric, Basalt Fiber Tape, Basalt Square Rope, Basalt Round Rop.
