- FFKM perfluoroelastomer
Product Overview
Seals in FFKM perfluoroelastomer, supplied for industries where chemical attack and temperature would destroy a standard compound. Applications include semiconductor manufacturing, pharmaceutical production, the chemical industry, petroleum and automotive work, and specialised sectors such as laser plating, battery manufacturing and special equipment production.
Key Benefits
- Withstands chemical and thermal conditions that degrade other elastomers
- Used in high purity sectors including semiconductor and pharmaceutical production
- Suitable for battery manufacturing and laser plating equipment
- Available across a range of seal profiles, not only O-rings
- Long service life reduces the cost of unplanned shutdowns
Problems It Solves
- Seals degrading under aggressive process chemistry
- Contamination risk in high purity processes from seal breakdown
- Frequent seal changes causing production downtime
- Compounds that cannot survive both the chemistry and the temperature

Compared With The Alternatives
| FKM seals | FKM covers most industrial chemistry at a much lower price; FFKM is specified when the chemistry or temperature goes beyond what FKM survives. |
|---|---|
| PTFE seals | PTFE is chemically inert but does not behave like an elastomer and will not recover in a dynamic groove; FFKM combines chemical resistance with elastomeric sealing. |
Use Guide
- Specify FFKM where downtime or contamination costs far exceed the seal price
- List every process chemical including cleaning and purge media
- Confirm whether a post cure is required for outgassing sensitive applications
- Keep a record of the compound grade for repeat orders
Questions
Questions Buyers Ask About This Product
Which industries use FFKM seals?
Semiconductor, pharmaceutical, chemical, petroleum and automotive, plus laser plating, battery manufacturing and special equipment production.
Do you supply profiles other than O-rings?
Yes, a range of FFKM seal profiles is available as well as O-rings.
Can you make a seal to our drawing?
Yes. Send the drawing along with the chemicals and temperatures involved.
Why is FFKM more expensive?
The base polymer is far more costly to produce. It is specified where the consequence of a seal failure is much greater than the seal price.
Is a post cure available?
Yes, where the application is sensitive to outgassing. Tell us at enquiry.
