UVICOM Co Ltd. produces various thermoplastic compositions on a basis carbon fiber reinforcing material. Carbon fibers are characterized by a unique combination is elastic- strength indexes, electro and heat conductivity, biological inertness and low density. Realization of these properties in polymers and the adaptability to manufacture inherent in thermoplast, allow to use these materials instead of nonferrous metals, and in some cases instead of steel designs when especially sharply there is a problem of corrosion firmness. The basic properties Thermoplastic carbon composites (TCC) that found application in various industries resulted in the table - The heterogeneous polymeric system consisting of a thermoplastic matrix (polyolefins, polyamides, polysulphons, etc.), reinforced by a carbon fibre (the maintenance reinforcing material from 5 to 40 % of weights)
- Issued in the form of black granules with a length 3-6 mm and diameter no more than 3 mm.
- Mass fraction of a moisture no more than 0,2 %
- Half-finished product for manufacturing of details of technical appointment by a molding method under pressure, injection molding and tubing.
The material has following indicators of quality (for examples are used carbon polyamide plastics)

Main efforts of ours engineers and technologists are focused not on creation of a universal material, but on the offer of necessary assortment to the industry. Due to such a concept and taking into account raw polymeric base existing in Russia, compositions on the basis of polyamides and polyolefins have been developed.
