Structural fibres spun from melted basalt
Basalt fibers are produced from basalt rocks by melting them and converting the melt into fibers.
Basalts are rocks of igneous origin. The main energy consumption for the preparation of basalt raw materials to produce of fibers is made in natural conditions.
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.
