Expanded PTFE - EPT 200
Expanded PTFE - EPT 200
Description
Technical Specification
100% multi-directionally expanded PTFE (polytetrafluoroethylene). Expanded PTFE has better creep resistance properties compared to skived/sintered/normal PTFE due to higher tensile strength.
Suitable for
SPITMAAN® EPT 200 expanded gasket sheet material is suitable for practically all applications in process industries within the temperature and pressure range.
Appropriate Medium
Steel & Iron, Fertiliser, Refinery, Chemical, Paper & Pulp, Sugar, EPC, Pharmaceutical, Power, Textile, OEM, Petrochemical, Food.

Notes
- For applications outside the typical use range, SPITMAAN® recommends engineering design calculation to specific application and extra care to be taken during installation. Uniform torquing during installation using ASME recommended methodology is mandatory. Retorquing after a thermal cycle should be done after cooling down of equipment is recommended. Please contact SPITMAAN® if further guidance is required.
- Except molten alkali metals and elemental fluorine.
