Expanded PTFE Gasket Sheet

We are offering expanded ptfe gasket sheet.
Ptfe has long been established for its excellence in chemical
resistance and for being inherently hygienic, non-toxic and
non-tainting. In operational use however it does have some
shortcomings; being susceptible to creep under cold conditions
and lacking dimensional stability when subject to thermal and
pressure cycling.
With multi-directionally expanded ptfe, however, a complex
thermo-mechanical stretching process changes the
conventional monoaxial structure of expanded ptfe into a
highly fibrillated multi-directional fibre structure, which results in
excellent dimensional stability and a further reduction of coldflow
and creep without the addition of filler materials.
This provides better sealing at higher pressuretemperature
combinations than possible with conventional ptfe gaskets.
Both at room temperature and at elevated operating
temperature, creep deformation strain is almost eliminated.
All the positive qualities of expanded ptfe - like excellent
malleability which compensates for damage and irregularities
on the sealing area, as well as the unsurpassed chemical and
thermal resistance of ptfe - remain unchanged
