Following the development of fluoroelastomers (FKM) in the 1950s, demand grew for a more chemically resistant polymer with the ability to withstand higher temperatures. As such, perfluroelastomers (FFKM) were borne out of this necessity in the late 1960s, combining the chemical resistance of PTFE with the flexibility and elasticity of regular FKMs.
Initially manufactured for chemical processes and space programmes, the versatility and durability of FFKM quickly saw it rolled out across a much wider range of applications. It is now widely used, particularly in the automotive and aerospace industries, to reduce downtime across many industry processes.
TRP Polymer solutions have developed a range of FFKM materials suitable for a huge variety of industries and applications. O-rings, seals and gaskets are the most common products that we manufacture from FFKM. In pursuit of excellence, we developed our unique TRPlast range of Perfluoroelastomers (FFKM). Put simply, this range of perfluroelastomers offers the highest levels of performance and can often be used in applications where other polymers simply wouldn’t cope.
FFKM O-rings offer exceptional chemical and thermal resistance. They combine the sealing force, resistance and recovery characteristics of a regular elastomer O-ring with the added chemical resistance of PTFE. 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 finished O-ring products.
An increase in fluorine content increases the chemical resistance of hydrocarbons. As such, FFKM contains 72.5% fluorine with a fully fluorinated backbone chain, which is the maximum fluorination possible whilst still retaining the elastomeric properties required for sealing systems. FFKM’s ether group (R-O-R) gives it its elastomeric properties and elasticity, without which FFKM would act much the same as PTFE.
TRP Polymer Solutions have developed a range of FFKM materials offering the highest levels of performance, which in turn extends the service life of all our FFKM O-rings.
