GFO Packing

Carbon Fiber Packing Impregnated PTFE

Carbon fiber packing, also known as Pre Oxygen wire packing, is manufactured by heating polyacrylonitrile fiber into the carbonized fiber. The surface is made of PTFE emulsion and lubrication treatment. Carbonized fiber packing has excellent thermal conductivity, wear-resistance, and chemical stability, and is relatively cheap in non-asbestos products. It is an ideal asbestos substitute.

  • Application Device:
    Sealing of valves, pumps, flanges, mixers, mixers, stern shafts, etc.
  • industry:
    Industrial equipment such as petroleum, metallurgy, chemical industry, fertilizer, power generation, instrumentation, etc.

Order Details About Carbon Fiber Packing

As a professional gland packing manufacturer,  there are 2 types of carbon fiber packing in Ginseal Factory:

  1. Carbonized PTFE packing impregnated in graphite
    • Item No.: JSP-CB10
    • Carbon fiber packing with graphite is woven of strong carbon fiber
      After softening treatment and impregnation with mixture latex of fine graphite powder, PTFE dispersion and lubricant. It is chemical resistant, heat conductive and with high strength, so this item is widely used with revolving and reciprocating pumps in which chemical corrosive media and particle grains exist. It’s the best sealing material for high pressure a, high temperature and corrosion.
      When the gland packing is used for pumps, frictional heat is freely conducted to the stuffing box metal by its excellent thermal conductivity with no or little damage caused to the shaft sleeve or to the packing.
  2. Carbon fiber packing impregnated PTFE
    • Item No.: JSP-CB20
    • Carbonized fiber packing is a particularly flexible combination of high-quality carbon yarns and PTFE-yarns, diagonally braided with special PTFE compound and impregnated with running-in lubricant.
