Graphite / PTFE composite yarn for demanding sealing duty.
Graphite PTFE packing is a specially engineered yarn combining graphite and PTFE. As both materials are excellent sealants, the composite delivers sealing properties that neither material offers alone: wide chemical resistance together with low friction and high thermal conductivity.
