Learn about the impressive properties and resistance of FFKM O-rings.
FFKM O-rings offer exceptional chemical and thermal resistance.
FFKM (perfluoroelastomers) is designed to operate in the most severe conditions, suitable for a diverse range of O-ring applications. It has the highest temperature resistance of any elastomer material, up to 330°C and is a chemically resistant rubber equivalent to PTFE. However, it retains the sealing force, resistance, and recovery characteristics of a regular elastomer O-ring.
The carbon-fluorine bonds of FFKM, regarded as the strongest single bond in organic chemistry, guarantee the high chemical, thermal and oxidation resistance of our moulded FFKM O-rings. Perfluoroelastomers contain 72.5% fluorine with a fully fluorinated backbone chain, this is the maximum fluorination possible whilst still retaining the elastomeric properties required for sealing.
Our TRPlast® range of FFKM perfluoroelastomers designed, developed, and manufactured by TRP Polymer Solutions, provides sealing in harsh chemical environments at temperatures ranging from -45°C to +330°C. You can find out more about our materials and their individual FFKM material properties on our datasheets page.
TRPlast® FFKM O-rings can be supplied with lead times as short as 48 hours. For bespoke O-ring orders where tooling is required and for custom mouldings, parts may be supplied within 10-14 days.
FFKM’s material properties have many notable benefits, including:
FFKM has a higher temperature resistance than any other elastomer, withstanding up to 330°C.
FFKM poses great resistance against many chemicals, including ketones, fuels, esters and more.
As a result of its fully fluorinated molecular structure, FFKM can withstand oxygen-rich environments.
TRP produces technical rubber moulded products for aerospace and defence industries, with solutions for military and commercial applications.
