Virgin – Unfilled P.T.F.E. (Also known as Teflon) is a unique thermoplastic and is resistant to almost all corrosive chemicals, except for alkali metals.  It has the lowest coefficient of friction of all materials and a slippery surface to which no substances will adhere.  It is the perfect material for environments where the use of lubricants is not desirable.  PTFE has the widest working temperature range of all plastics, from -270°C to 260°C, and is excellent for use in cryogenic applications as it shows no brittleness.  PTFE (Teflon) has very good sealing properties and is not flammable unless in a 94% oxygen environment.

Virgin – Unfilled PTFE is not ideal in high wear abrasive applications or in high loading applications.  Here filled PTFE grades are used to improve resistance to load and wear.  Alloys and Fillers – 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.
