Application area: General industry


General facts

Polytetrafluoroethylene

Shortening: PTFE

Color: White

Common uses: Electrical applications in aircraft, robots, electrical machines, gaskets, pipes, filters, self-lubricating bearings, coating in pans, foil, surface coating in chemical equipment, electrical insulation material, etc.

Benefits

  • High chemical resistance.
  • Not attacked by acids, bases and most organic solvents.
  • Withstands up to + 260 ° C continuously.
  • Tough at low temperatures down to -160 ° C. • Lowest friction of all plastics.
  • Not degraded by UV radiation. • Not attacked by microorganisms.
  • Good electrical and dielectric properties.
  • Very low water absorption.

Restrictions

  • High melt viscosity makes the material difficult to work with.
  • Poor creep resistance.
  • High density relative to other plastics.
  • Attacked by molten alkali metals, fluorine gas, oxygen difluoride and chlorine trifluoride (except PTFE).
  • Low abrasion resistance.
  • Limited load capacity.

Specific properties

Fluorescent 135 has been developed to offer a combination of low friction and high bearing capacity in constructions with sealing rings, bearing bushings and washers. Use in compressors, piston rings in pumps and valves, makes this material a first choice even in unlubricated applications. Fluorosine 135 also offers the lowest coefficient of friction and coefficient of longitudinal expansion compared to other modified PTFE materials. In addition, the material has the highest chemical resistance and can withstand temperatures up to approx. + 230ºC during continuous operation.
