Polytetrafluoroethylene (PTFE) seals and piston rings have started to replace their carbon counterpart as PTFE seals and rings offer greater durability, have a longer operating life, and can be operated at various pressures, velocities and temperatures.
PTFE seals and rings are becoming more common in a variety of applications and industries because of the unique advantages they offer.
PTFE Piston Rings and Guide Rings (Rider rings) for dry-running applications are currently a focal point of technical development.
They significantly reduce a machine’s operating costs and, in today’s increasingly environmentally aware society, make it easier for operators to fulfill stricter environmental legislation.
Properties
Exceptionally low friction coefficient in combination with metals and plasticsAntiadhesive behavior without any stick-slip effectHigh elongation properties enabling easy fitting of sealing and guide rings to one-piece pistonsExceptionally large temperature range from –200°C to +260°CChemically resistant to almost all solid, liquid, and gaseous mediaAgeing-resistantNonflammablePhysiologically neutral in the stated temperature range
Suitable for the Following Application Areas
