Basalt Continuous Fiber (BCF) is a raw material for production of various types of materials & products.
Basalt fibers are well compatible with other materials & fibers, and therefore they are good for production of complex materials.
The special attention should be paid to the composite materials made of BCF with carbonic fiber, as well as to application of BF as a reinforcing material for concrete and asphalt concrete structures. CBF & carbonic fiber composite materials have outstanding features and, besides that, they are much cheaper than pure carbonic fiber materials. This makes it real to use them for wide range of applications.
High durability of basalt fibers towards high temperatures, acids and especially alkalis is widely known (See BCF Information & Characteristics). This allows using basalt fibers in a very wide range of construction works, such as:
• Reinforcing material for concretes & asphalt concrete covering for roads, airport runways & taxiways.
• Corrosion & chemical durable reinforcement, which strength exceeds that of alloyed steel by far;
• Noncombustible & fire-resisting complex materials for nuclear and thermo electric power stations, oil processing & chemical plants, high buildings & important industrial structures fire walls for fire spreading prevention;
• Chemical durable & antiwear coating, composites;
• Filters for industrial & residential waste waters, filters for smoke & dust emissions of industrial enterprises (See article Filters);
• Material for car manufacturing (See article Application of basalt fiber in car manufacturing).
• See chapter Applications of BCF materials

Basalt super thin fibers (BSTF) materials
BSTF are layer staple fibers with diameter of 1~3 microns, mixed and fastened among themselves, the regular form of this product is felt (felt of basalt wool). Many sound-proof& thermo-insulation materials are made from BSTF canvas (felt), including mats, needle canvas, cardboard, soft& hard slabs.
Advantages of BSTF:
1. It’s made only from basalts, not any other materials;
2. It has good heat-insulation qualities;
3. The material is absolutely nonflammable, it has high thermo durability.
Temperature of long application is up to 700 C, temperature of short-term application is up to 1000 C;
4. High chemical durability towards water, salt solutions, alkali and acids;
5. High sound-proof characteristics and durability to vibration;
6. The material is made without application of glue or on the base of inorganic glue;
7. Under heating or open flame the material does not evolve any toxic substances;
8. The material has low hygroscopic quality, eight times below of that of fiber glasses;
9. High durability of operation even in damp conditions.

Basalt scales (BSc) materials & covering
Basalt scales (BSc) is a thin lamellar material with thickness 2~6 micron and area of a surface around 0.5~4.5 mm. Basalt scales owes it’s name to the scale of fish, because they have similar protective qualities. BSc is a unique material for production of protective, wear proof, anticorrosive & chemically proof coverings, reinforced composite materials, reinforced plastics, frictional materials (such as brake blocks & clutch plates). Wear resistance & chemical stability of lacquer coatings reinforced by BSc increases several times. Durability of reinforced by BSc plastics increases 2~3 times. Application of BSc together with inorganic couples (glues) allows creating nonflammable heat-resistant coverings with temperature of application of up to 700 C. Coverings with BSc are applied by spraying, it adds efficiency to equipment.
High-temperature Composite Materials
High-temperature composites
The company has developed advanced technologies for high-temperature materials production, as well as production with application of the so called "cold" technologies. The core of these technologies lies in the idea of high-temperature materials production with application of "cold" technologies, without using traditional baking techniques. At the same time, the new high-temperature composite materials (HTCM) have new features:
• Low specific density – from 300 to 1200 kg/m3;
• High heat-insulation properties;
• Stable towards drastic temperature differences;
• Easy for forming and machine processing during creation of products with complex shape.
Field experience of high-temperature composite materials application, including the experience gained in China,
has shown their high characteristics & operational features, which make them good for fettle works & furnaces repair works, manufacturing gas & liquid-fuel jets stones, and, especially, for fettling bushing in basalt & glass fibers production.
