PTFE – Polytetrafluoroethylene

PTFE is a fluoropolymer characterised by a high resistance to solvents, acids and bases and UV. PTFE, often referred to by the trade name Teflon (DuPont), is well known for its application in non-stick cookware, PTFE is one of the most thermally stable plastic materials retaining most of its properties up to temperatures of 260°C. One of PTFE's most recognisable and desirable traits is its extremely low coefficient of friction making it a material of choice in sliding parts.

PTFE also displays exceptional chemical resistance and dielectric properties and is considered to be a good insulating material. It is resistant to most acids and bases and insoluble in almost all solvents up to 300°C. PTFE is often found in parts used in the petrochemical and chemical industries.

However, PTFE has poor mechanical properties and is often modified with fillers of glass or carbon to improve dimensional stability.

Benefits:

  • High resistance to chemicals.
  • Resistant to both low and high temperatures.
  • Low flammability.
  • Low coefficient of friction.
  • High UV resistance.
  • Good electrical properties.

Forms: Rod and sheet - Colour natural (white)

Virgin PTFE
Colours: Natural (white)

PTFE-GF (Glass-filled)
Colours: Natural (off-white)
Glass filled PTFE increases wear and creep resistance when compared to unfilled (virgin) PTFE.  Its chemical resistance remains largely unaffected.

PTFE-CF (Carbon-filled)
Carbon filled PTFE offers improved wear and creep resistance in comparison to unfilled PTFE. Carbon filler improves dimensional stability, raises the heat deflection temperature, improves creep resistance and the dynamic bearing performance.
