PTFE (Teflon)

PTFE sheet, rods, cylinders and tube are resistant to practically every chemical known to man and has a surface as slippery as ice to which no substance will adhere. PTFE will operate continuously at 260°C in harsh conditions for long periods. It will also not degrade when exposed to long term sunlight.

Advantages of Virgin PTFE material include:

  • Unaffected by almost all chemicals
  • Continuous use at high temperatures
  • Slippery non-stick surface
  • Outstanding dielectric properties

As the need for more demanding uses emerge, PTFE can be customised by the addition of fillers to create PTFE compounds with enhanced physical properties to suit particular mechanical applications outside the scope of virgin PTFE.

Advantages of PTFE compounds include:

  • Improved resistance to cold flow or creep
  • Reduction in Wear and Friction
  • Improved dimensional stability
  • Increased stiffness and surface hardness

PTFE sheet, rod, cylinders and tube include:

  • PTFE S Unfilled, natural
  • PTFE G – Higher compressive strength abrasive wear
  • PTFE HG – High percentage glass filled PTFE for reduced creep and wear
  • PTFE C – Highest wear and creep resistance
  • PTFE B – High wear and abrasion resistance, reduced chemical resistance

Properties of PTFE sheet, rod, cylinders and tube include:

  • Excellent chemical resistance
  • Lowest co-efficient of friction
  • Highest operating temperature and stability
  • Physiologically inert
  • Excellent electrical properties

Applications of PTFE products include:

  • Seals
  • Seats
  • Packing
  • Chevrons
  • Piston rings, glide rings, lantern rings and back up rings
  • Slide bearings
  • Electrical and thermal insulators
