CGFO the fibre represents two-layer graphitic fluoroplastic a string with a graphite insert inside. The given string contains more graphite, in comparison with usual graphitic fluoroplastic a string because graphite is in an environment. Free particles of graphite on a surface are absent. Packing has very low factor of friction and good heat conductivity due to an additional graphite insert.
Approaches in use in exchange graphitic fluoroplastic packings in units of friction with the raised speed and temperature. This self-greased packing which does not do furrow on a shaft and minimizes charges on restoration. Can be used as an isolating layer in autoclaves, mixers, pumps, etc., at contact to alkalis, solvents, water, the ferry, acids, oil, except for strongly concentrated acids (nitric, sulfuric, etc.) and liquid alkaline metals.
