FFKMs Protect Components in Enhanced Oil Recovery

FFKMs, also known as perfluoroelastomers, were first developed in the 1960s for applications involving high temperatures and/or aggressive chemicals.  Perfluoroelastomers exhibit many properties similar to PTFE (polytetrafluoroethlyene, or Teflon®), and are considered inert in almost all solvents.  However, PTFE is a plastic, and when compressed, it will not recover to its original shape.  On the … Continue reading FFKMs Protect Components in Enhanced Oil Recovery

New FFKM Extends Seal Life

Article re-posted with permission from Parker Hannifin Sealing & Shielding Team. Original content can be found on Parker’s Blog.
