Basalt fiber - produced from mineral fertilizers (basalt
rocks) by melting and turning the solution into fibers.
Basalt fibers are a natural raw material of magmatic
origin. Continuous fiber, staple fiber, short fibers and
thin fibers are produced and used from basalt raw
materials. Continuous fibers, solid and composite
materials and products, fabrics and non-woven
materials, heat-insulating fabrics and plates, thin fibers,
high-quality heat- and sound-insulating fabrics (fabrics,
plates, cardboard), filtering materials are produced
from basalt fiber. Basalt fibers are produced from
igneous basalt rocks. In addition, basalt fibers are
resistant to moisture and have high fire resistance.
Basalt fibers have a diameter of 8 - 20 microns, the
length of the fibers is 25 - 50 kilometers and more. The
diameter of the elementary fibers is 6 - 12 microns, the
length is 5 - 12 mm. Fine basalt fibers (STBF). The
elementary diameters are 0.5 - 3 microns, the length is
10 - 50 mm. The continuous fibers of basalt solutions
have much higher strength properties. The tensile
strength of basalt fibers is from 2800 to 4800 MPa.
Basalt fibers are highly resistant to chemically active
substances (acids, alkalis, salt solutions) as well as to
high temperatures and open flames. Resistance of
basalt fibers to ordinary drinking water and sea water
is 100%, alkalis 96% and acid 94%. Due to the high
strength of basalt fibers and their high resistance to
chemicals, they are used in the production of concrete
and asphalt concrete reinforcement, pipelines,
reservoirs for the chemical and petrochemical industry,
hydraulic
engineering,
coastal
and
marine
construction. Basalt fibers can be used for a long time
at temperatures from 200 C to + 600 C. Basalt fibers are
fire-resistant, they are also resistant to temperature
effects of + 90, ... + 1200 C during a fire. Heat-insulating
and fire-resistant materials based on basic and ultra-
thin fibers withstand normal fire, do not emit smoke
when heated and exposed to flame. The
hygroscopicity of basalt fibers is 6 times lower than
that of glass fibers. In the aviation and shipbuilding
industry, heat- and noise-insulating materials based on
very thin basalt fibers are used, because they do not
absorb excess moisture, do not burn, and are resistant
to high temperatures. Basalt fibers are used in the
production of insulating fabrics for dielectrics,
electromagnetic radiation, radio rays and magnetic
fields, as well as in the production of antennas. These
properties make basalt fibers more durable than glass
fibers and chemical fibers. Basalt fibers are more
resistant to erosion and other microorganisms. Fabrics
made from basalt fibers are widely used in the
construction industry, automobile industry, aviation
industry, shipbuilding and energy industry. Basalt
texture is a very important raw material in these
industries due to its durability and strength, as well as
heat resistance. The properties of basalt fibers, their
strength, fire resistance, resistance to various external
influences and chemical substances, increase the

fabrics.
