Basalt fabrics for electro technical purposes are used as a base for the production of insulation materials. These materials are employed in the production of substances for printed circuit boards for electronics and electrical engineering. These have superior properties to similar conventional components made of fibreglass. General-purpose fabrics are useful, for example in fire feltings for suppression of extremely complex fires resulting from ignition of highly flammable liquids, in particular gasoline. The employments of incombustible basalt fabric inserts in industrial ventilators increase their fire safety as well as the fire resistance of ventilating systems. The cost of basalt fabrics is considerable lower than that of similar materials. The non-combustible properties of basalt woven materials enable it to resist flames for long periods that make basalt tapes effective as an extra fine resistant insulation for electrical cables and underground ducts. Basalt-fabrics hoses may be useful for reinforcing cables, repairing the interior and exterior of tubes and pipelines.
