  • Average Tensile Modulus 60 GPa;
  • High elasticity;
  • High chemical stability to acids, alkali, solvents (at normal & high temperatures);
  • Possibility of processing on the textile equipment;
  • Electrical conductivity.

APPLICATION

Examples are based on present state of knowledge we have. Material’s unique properties allow other problems also to be solved. It is a reason of close cooperation with users and processing companies when needed.

  • Packing and sealing industry;
  • Ablative composites;
  • Cord, electrical conductor, carbon-carbon composites, carbon ceramics;
  • Si-ingot industry: crucible susceptors in the form of basket (CZ-process);
  • IR-heaters;
  • HS-215 is sewing (binder) yarn for felt, fabric.
