PTFE (Teflon) Machining

A Guide to PTFE CNC Machined Parts: Properties, Applications and Design Considerations

What is PTFE?PTFE Machined Part

PTFE (Polytetrafluoroethylene) is a semi-crystalline fluropolymer thermoplastic. It is commonly referred to as Teflon which is a brand name.

PTFE is the most widely used fluropolymer in a range of applications. It is known for being highly resistant to chemicals and for its superior thermal stability.

Compared to other engineering grade thermoplastics it has poor mechanical properties, though glass and carbon filled grades with improved dimensional stability are available.

Because of its resistance to chemicals, PTFE is commonly used in chemical, food and pharmaceutical engineering.

PTFE is favoured over PVDF for sliding applications with exposure to extreme chemical stress.

Main Attributes of PTFE:

  • Excellent chemical resistance
  • Good electrical insulating properties
  • Wide working temperature from -260°C to 260°C
  • Very low coefficient of friction
  • Poor mechanical properties – glass and carbon filled modifications available to improve dimensional stability
  • Low flammability
  • High UV and weather resistance
  • Suitable for food contact
  • Water resistant
  • High impact strength
  • No moisture absorption
