Basalt fiber

Basalt fibers are produced from basalt rocks by melting them and converting the melt into fibers. Basalts are rocks of igneous origin. Basalt fibers are classified into 3 types:

  • Basalt continuous fibers (BCF), used for the production of reinforcing materials and composite products, fabrics, and non-woven materials;
  • Basalt staple fibers, for the production of thermal insulation materials; and
  • Basalt superthin fibers (BSTF), for the production of high quality heat- and sound-insulating and fireproof materials.
