XFluor® PFX8014

A high-purity white FFKM for processes where cleanliness, visual control and sealing reliability come first. PFX8014 combines an ultra-clean identity with the chemical and thermal performance of perfluoroelastomer technology, across a stated temperature range from -5 to +250 °C.

Long description, Tables, Technical sheet, other​

XFluor® PFX8014 is the high-performance white solution in the NEXA range. It has been developed to combine outstanding chemical resistance, thermal stability and elasticity with a clean, light-coloured and immediately recognisable formulation – a practical advantage in processes where material identification and visual control play a central role.

With a minimum tensile strength of 17 MPa, minimum elongation at break of 140% and maximum compression set of 25% after 72 hours at 200 °C on an O-ring #214, PFX8014 delivers solid and reliable performance in demanding industrial processes. It is the natural choice when a conventional black compound is not aligned with the level of cleanliness, appearance and control required by the application.

Recommended applications

  • O-rings and seals for pumps, valves and dosing systems;
  • chemical plants and high-cleanliness process equipment;
  • analytical instrumentation and components where a white, easily identifiable compound is preferred;
  • machinery and process systems for the pharmaceutical, cosmetics and food industries;
  • high-temperature applications involving aggressive fluids;
  • processes where visual control, product appearance and equipment cleanliness are key differentiators.
