Expanded PTFE / Teflon Sheet
The exceptional malleability of Expanded PTFE compensates for out-of parallel and/or damaged sealing surfaces and allows use with stress sensitive connections and applications where only a limited flange load may be available.
Typical applications are the sealing of flanges, pump housings, compressors, hand and manholes, air ducts, compensators, heat exchangers and many more.
Expanded PTFE material is supplied in sheets with width 1500mm x Length 1500 mm. These can be further punched into smaller gaskets as required by the end-user. Yureka offers the option of supplying both the cut gaskets as well as the full sheet.
Temperature rang : 240°C up to +260°C, for short periods up to +310°C
Chemical resistance : resistant against all chemicals from pH 0-14 – except molten alkali metals and elemental fluorine at high temperature and pressure
Aging resistance : Itself does not age and is UV-resistant.
