TEFLON® / PTFE FOAM GASKET – TEFOM TM
In Developing TEFOMTM our objective was to provide the chemical Industry
in particular, with a universally applicable Gasket material offering
substantially better characteristics than coventional gasket material.
In order to cover the range of possible applications TEFOMTM sheets
and rings dark grey in colour was developed.
Product performance and technical data have been determined and checked
in numerous test series. Our tests were carried out under diffcult
conditions of pressure and temperature variation over peorods of several
weeks. The extremely low leakage figures should be assessed against
this background.
TEFOMTM is a modified PTFE which is supplied in flat from
which seals can be punched or cut in ring form or

In addition to the
standard applications - TEFOMTM is particulary suitable
where sensitive flange materials, such as glass or ceramic, and
could be damaged by other excessively hard seal materials.
TEFOMTM is extermely resistant to various media and is insensitive to frequent
load alternation. It is adaptable over the whole temperature range
between - 3500C and +2600C. It can deal reliably
with pressure upto 40 bar.
TEFOMTM has been use with gaseous oxygen at pressure upto 40 bar and at
temperatures upto 2250C.
