2 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. Novgorod Moscow Chelyabinsk Minsk Ulyanovsk Germany Ukraine Tomsk Novosibirsk Bulgaria Krasnodar Tashkent Vladivostok Research and manufacturing facilities Moscow Klimovsk, Moscow region New technologies and materials development, sealing and fire-protective products manufacturing, customers services, sales office Kirovo-Chepetsk Raw materials processing, semi-products manufacturing Novosibirsk Fire-protective doors manufacturing, сustomers services, sales office Sales Office and Dealers

3 UNICHIMTEK in numbers Foundation year 1990 Staff number 540 Production facilities 28,000 m 2 Product range over items Over 5000 customers: Nuclear and thermal power plants Oil and gas industry companies Chemistry and pulp and paper companies Machine engineering companies Motor plants Russian Railways UNICHIMTEK has developed the full technological cycle of natural graphite processing from refining to manufacturing of the wide range of sealing and fire-protective materials and products. Chemical refinement Thermal refinement 2970 o C Refined graphite 99.0%, 99.9% Natural graphite 93.0% Refined Graphite special treatment Oxidated (intercalated) Graphite with expansion temperature from 120 o C Super-refined graphite 99.99% Thermal treatment Fire-Protective Products Expanded Graphite Mesh Paste Sections Sheets Rolls Pillows Sorbents Fuel cell Carbon carbon composites Spiral-Wound Gaskets Reinforced Sheets Sealing Products Gaskets Gland Rings Braided Packings Graphite Foil Carbon Content up to 99.9%

4 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 R&D department and quality control laboratory 0.90 Density (g/cm 3 ) Online monitoring of foil density in 6 points using patented technique (no radiation)

5 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 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 > % < 200 ppm *Special properties are available upon request

6 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.

7 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

8 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

9 TENSOGRAPH P Ultra-Pure Graphite Foil UNICHIMTEK has developed original technologies and equipment for natural graphite purification. Our graphite products are traditionally characterized by low level sulfur and chlorine contents. On customer request we may supply 99.5% and 99.9% grade materials for application in: Nuclear industry Lithium batteries andfuel cells Special applications Products to be delivered in form of rolls, sheets and laminates with tanged stainless steel insert Patent pending. Typical properties* of TENSOGRAPH High purity graphite foil Carbon content Ash content Density Thickness Tensile Strength Sulfur content Chlorine ion content Width of rolls, sheets Grade 1 Grade 2 >99.5% >99.9% <0.4% <0.1% g/cm mm >4 MPa <200 ppm <100 ppm <30 ppm <20 ppm Up to 1500 mm *Special properties are available upon request

10 TENSOGRAPH L Low-density expanded graphite panels Grace to amazing ability to modify density of expanded graphite the materials with aimed physical properties could be developed. UNICHIMTEK group is glad to share own expertise to offer light-weight materials with improved mechanical properties, electrical and heat conduction, impurity content, surface activity etc. Applications: Thermal management Filters, adsorbents Refractories for high temperature apparatus Electrodes for hydrometallurgy Patent pending Typical properties* of TENSOGRAPH L Low-density expanded graphite panels Density Thickness Flexural strength Thermal conductivity Carbon content Ash content Sulfur content Chlorine ion content Width 0,03 g/cm 3 Up to 40 mm MPa W/m*K >99.5% <0.4% 200 ppm <30 ppm Up to 1500 mm *Special properties are available upon request
