CARBON & GRAPHITE FELT «CARBOPON» RAYON BASED

EATURES

  • Stability in inert (oxidizer-free) ambience 3000°C max;
  • The lowest level of thermal conductivity (in comparison with PAN or pitch based felts);
  • Stability in oxidizer ambience 400°C max;
  • Insensitivity to electromagnetic, nuclear and space radiation;
  • Filament Tensile Strength 1.2 - 1.5 GPa;           
  • Average Tensile Modulus 60 GPa;
  • High chemical stability to acids, alkali, solvents (at normal & high temperatures);
  • Electrical conductivity; radio wave adsorption.

APPLICATIONS

Examples are based on current information received from our customers. 
The unique properties of the material are constantly expanding its application.
We'll be glad to update this list with your ideas!

  • Vacuum or inert gases furnaces thermal insulation (CZ);
  • Hot zones heat-insulation;
  • Nuclear reactor technology (for neutrons absorption);
  • Filters for hot and (or) corrosive gases and liquids;
  • For molten metals (zero wetting);
  • Catalyst carrier;
  • 3D (high surface area) cathode for precious metals electrochemical extraction (Au, Pt, Pd, etc), especially for gold electrowinning;
  • Corrosion-resistant vessel linings;
  • Backing strips for soldering and welding (no wetting, no smouldering);
  • Electromagnetic wave absorber.
