Graphite yarn

Graphite yarn

 By manufacture of a graphite string various materials for its reinforcing are used. Termo-expanded graphite is used as the base material reinforced by natural fibres, synthetic fibres, a metal wire with addition binding elements. It allows to make from a string of  packing which can be used in various chemical environments, at various temperature and pressure.

  The string is issued following face values: 2g/m, 3g/m, 5g/m, 10g/m.
