Grades PTFE

PTFE is available in virgin & filled compounds to improve the basic characteristics to match very diverse application & optimization for specific end uses.  
Grades Filler content by weight Properties
Virgin PTFE ---- Excellent chemical Resistance, outstanding electrical Properties & Excellent flexural properties.
Glass filled PTFE 15-25% Higher compressive strength, Better wear resistance & Excellent chemical resistance.
Carbon / Coke filled PTFE 25-35% Higher compressive strength, Better thermal conductivity & Better wear resistance.
Graphite filled PTFE 0.15 Good chemical resistance, Higher compressive strength, Improve frictional properties.
Bronze filled PTFE 40-60% Good thermal conductivity, Very low cold flow Higher compressive strength, Excellent wear resistance.
Bronze plus Molybdenum Disulphide Filled PTFE 55+5% Improved frictional properties, Good thermal conductivity, Very low cold flow, Higher compressive strength & Excellent wear resistance.

  • The presence of filler generally causes following negative features in compounds
  • Reduction in tensile strength & break elongation
  • Reduction in volume & surface resistivity
  • Lower chemical resistance depending upon type of filler
  • Reduction in coefficient of linear thermal expansion
  • Difficulty in processing & fabrication
