The NEXA benchmark for high-performance industrial sealing. PFX8010 is a black 75 Shore A FFKM developed to deliver outstanding chemical resistance, thermal stability and reliability in demanding applications, with a stated temperature range from -5 to +260 °C.
Use the configurator to choose the correct material, size code, internal diameter and cross-section.
Open configuratorWhen process conditions exceed the capabilities of conventional elastomers, XFluor® PFX8010 takes sealing performance to the next level. Its highly fluorinated polymer structure combines the elastic response of rubber with excellent resistance to a broad range of aggressive chemicals, solvents and elevated temperatures.
Its well-balanced mechanical profile – including a minimum tensile strength of 18 MPa, minimum elongation at break of 140% and maximum compression set of 25% after 72 hours at 200 °C on an O-ring #214 – makes PFX8010 one of the most versatile solutions in the XFluor® range for handling thermal cycles, pressure and critical process fluids.
