Prime Features

  • Long maintenance free service life. Minimal shaft wear and leakage
  • Pliable, wear-resistant and dimensionally stable. Rugged and non-toxic
  • Extended service life by up to 400% in harsh environments.
  • Six times better heat conduction as against pure PTFE packing at comparatively high speeds.

Prime Features

  • Significantly low thermal expansion thus resisting ‘over expansion’ extrusion under service
  • Suitable to centrifugal & reciprocating pumps even at high pressure
  • Excellent in abrasive application. Well proven with aggressive media
  • High penetration & abrasion resistance of polyamide fibers ensure corner safety of packing
