FFKM is a family of perfluoroelastomer compounds that contain even higher amounts of fluoride than FKM. FFKM o-rings provide exceptional high temperature and chemical resistance, and can even withstand prolonged exposure to oxygen-plasma. FFKM o-rings can be provided for continuous service in temperatures as high as 621°F (327°C). These o-rings, etc., are commonly used in applications that involve repeated or prolonged contact with hydrocarbons and/or highly corrosive fluids, or those that encounter a wide range of temperatures and retention of sealing force are paramount; these Perfluoroelastomer ffkm o-rings are sure to impress our domestic as well as overseas clients. The unique production materials and impeccable quality of the product has helped it emerge as a favourite in the market. This has also helped us come forward as part of the popular Perfluoroelastomer ffkm o-rings Manufacturers.
FFKM perfluoroelastomer materials are specified by ASTM 1418 standard, and are equivalent to FFPMs by ISO/DIN 1629 standards.
Widely used in chemical processes where purity, high temperatures over 320°C and retention of sealing force are paramount; these Perfluoroelastomer ffkm o-rings are sure to impress our domestic as well as overseas clients. The unique production materials and impeccable quality of the product has helped it emerge as a favourite in the market. This has also helped us come forward as part of the popular Perfluoroelastomer ffkm o-rings Manufacturers .
Features of FFKM seals include
High temperature stability up to 327°C (620°F)
Almost universal chemical resistance
Outstanding mechanical properties
High purity materials
FDA, USP Class VI and 3A compliance
Highest quality parts
Applications: Widely apply to semiconductor, panel, and petrochemical industry. Apply to harsh environment, like etching, film process, high temperature, liquid, strong acid and base.
Why do we prefer FFKM over other material standards?
FKM vs. FFKM Comparison?
See a comparison chart for other material compounds here. . Our O Rings offer outstanding performance in demanding operating environments. The chemical and heat resistance of Perfluoroelastomer (FFKM) are similar to those of PTFE. It combines the positive properties of a PTFE O Ring with the elastic behaviour of FKM / Viton O Ring. Perfluoroelastomer / FFKM O Rings are only used if other materials cannot meet the very high application specifications. Typical applications for FFKM O Rings include the Chemical, Aerospace, Oil, High Vacuum Technology and Semi-conductor industries.
