About PTFE
Virgin P.T.F.E. is the most common form and has some unique features which, apart from its good slip characteristics, the advantages of this high performance product lies less in its mechanical than in its thermal, electrical and chemical properties. Unfilled P.T.F.E can be characterised by the following properties:
- Chemically inert
- Insoluble in all known solvents below 300ºC
- High thermal stability, continuous service temperature range -270º to 260ºC
- Low coefficient of friction
- Outstanding electrical and dielectric properties
- Resistant to stress cracking and weathering
- Limited use in structural components because of low modulus of elasticity
- Poor wear resistance
- Poor mechanical strength
- Very high specific gravity
- Easy to machine
Specification
Skived sheet, rolls and tapes are produced by peeling a PTFE cylinder using a similar
process to manufacturing wood veneers. A PTFE cylinder is pressed onto a mandrel
and mounted onto a lathe. A special cutting tool is mounted onto the cross slide which
at a constant speed advances towards the PTFE cylinder skiving off a continuous film
at a constant thickness.
