History and Prospects

Our mission is to enhance the efficiency of customers business, to ensure the safety of people, to save resources and to protect environment through scientific research and innovations introduction History and Prospects Our history dates from 1979, when the research in the field of new synthetic metals on the base of graphite intercalation compounds had been launched in the Lomonosov Moscow State University. In 1986 the Laboratory of the Chemistry of New Carbon Materials had been established; the main task of the Laboratory was to develop structural materials for aerospace applications. In 1990 UNICHIMTEK had been founded on basis of the Laboratory. Today UNICHIMTEK is the leading Russian company in the field of development, manufacturing and promotion of innovative sealing and fire-protective materials and products. Our success is based on permanent improvement of materials and technologies, quality control, and expanding research and development areas. In addition to our traditional business areas we are glad to provide our solutions in the following fields: Thermal insulation and heat management products Fiber reinforced composite structural materials Resins and textile preforms for composites manufacturing Moscow State University - one of UNICHIMTEK founders St Petersburg Kirovo-Chepetsk N.

UNICHIMTEK Production Facilities: Technology and facilities for graphite purification/intercalation 8 production lines of standard and reinforced graphite foil ( up to 1500 mm wide). All lines are equipped with online quality control ( both in length and width) Multiple equipment and tools for production of graphite laminates and sheets, spiral wound and cam profile gaskets, pressed O-rings, braided packings, etc. Equipment for production of fireprotective materials 1.10 1.05 1.00 0.95 R&D department and quality control laboratory 0.90 Density (g/cm 3 ) 0 5 10 Online monitoring of foil density in 6 points using patented technique (no radiation)

TENSOGRAPH S Ultra-Strong Graphite Foil Graphite foil made of expanded graphite reinforced by carbon fibers. Tensile strength is > 20 times larger than for standard grade graphite foil. Patent pending. 15 20 25 L, m Typical properties* of TENSOGRAPH S Ultra-strong graphite foil Tensile strength, N/mm 2 (along rolling direction) Compressibility,% Recovery, % Density, g/cm 3 Thickness, mm Carbon content Sulfur content Width of rolls, mm >100 >35 >7 0.8-1.4 0.2-1.0 98 % < 200 ppm 3-600 *Special properties are available upon request

TENSOGRAPH S for Spiral Wound Gaskets Excellent filler for production of high quality spiral wound gaskets. ADVANTAGES: Increased production rate High strength - no break-up of filler Tight winding for production of more rigid SWG Minimal losses of material Low sulfur content Grace to its properties the use of TENSOGRAPH S foil as SWG filler allows to maximize the productivity and efficiency of automatic equipment for SWG production and is recommended for manufacturing of large diameter SWG (over 2 meters). Since 2011 TENSOGRAPH S is used as spiral wound gaskets filler at UNICHIMTEK production plants in Russia. SOME FACTS OF TENSORGAPH S APPLICATION: Production rate in creased by 30%. Materials yield ratio in creased from 80 to 95%. Total production costs reduced by 14 % compared with standard grade graphite filler application.

TENSOGRAPH S for Braided Packings New type of yarns for high quality braided packings. Reliable performance of TENSOGRAPH S braided packings in extreme conditions is due to combination of excellent heat dissipation and anti-friction properties of expanded graphite and ultimate strength of carbon fibers. Best solution for high temperatures and maximal pressures. Good alternative for graphite and carbon fiber packings. ADVANTAGES: Very high strength of yarns Low friction provided by expanded graphite Effective heat dissipation Operating temperature up to 723K Low sulfur content Lower costs in com parison with carbon fiber braided packings

TENSOGRAPH S for Packing Rings High strength and 3D reinforcement ensure the improved performance of pressed packing rings made of TENSOGRAPH foil in high pressure conditions. Because of unique elastic response more uniform distribution of tension could be achieved. ADVANTAGES: Improved sealing properties Steady operation of automatic equipment for O-rings production Extended pressure/temperature range No break of the ring during compression Could be used in worn stuffing boxes

TENSOGRAPH P Ultra-Pure Graphite Foil UNICHIMTEK has developed original technologies and equipment for natural graphite purification.
