PTFE Index

PTFE - an acronym for Polytetrafluoroethylene - is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded to other materials. Commonly referred to as Teflon - PTFE has extremely low coefficient of friction

Main properties of our range of PTFE sheet, rod and tube are:

  • high heat resistance
  • high resistance to chemical agents and solvents
  • high anti adhesiveness
  • high dielectric properties
  • low friction coefficient
  • non-toxicity.

PTFE is generally considered a thermoplastic polymer; at 327°C it maintains a very high viscosity, thus requiring particular transformation techniques for manufacturing of finished and semi-finished goods.

PTFE can be used at any temperature from -200°C to +260°C

The following grades of PTFE are available to buy online - please select from:

PTFE (Virgin Grade)

This virgin grade PTFE, and its advanced properties make it an ideal choice of material for a wide range of applications - particularly those requiring high temperature, chemical resistance and excellent slip-stick performance

Available colours:
 White

Available to buy in:
 Sheet: 0.25mm to 100mm thick   Rod: 4mm to 300mm diameter  Tube: various OD x ID diameters

25% Glass Filled PTFE

PTFE is reinforced with 25% glass fibres. The added glass fibre improves the wear properties and, to a minor degree, also the deformation strength under load while leaving substantially unchanged the electrical and chemical characteristics. However, it is important to remember that glass, has a rather poor resistance against alkalis and is easily attacked by hydrofluoric acid. The coefficient of friction is also slightly increased.

Available colours:
  Off-White

Available to buy in:
 Sheet: 1.5mm to 60mm thick   Rod: 6mm to 200mm diameter  Tube: limited range of OD x ID diameters

25% Carbon Filled PTFE

25% carbon is added to the PTFE, along with a small percentage of graphite. The carbon tends to improve - to a considerable degree - wear and deformation strength, whilst leaving the chemical resistance practically unchanged, but substantially modifying the electrical properties

Available colour: Black    Available to buy in: sheet and rod

Other Filled PTFE Grades

PTFE, because of the properties previously described, is used in many applications. Properties can be improved and/or modified by adding suitable fillers. The fillers most commonly used are: glass fibre, carbon, bronze or graphite, in the form of powder intimately mixed with the PTFE; other fillers are: molybdenum bisulphide, metal powders, ceramics, metal oxides and mixtures of two or more additives.

Available colour:  according to filler     Available to buy in:  sheet, rod and tube
