FFKM film. FFKMs (by ASTM 1418 standard) (equivalent to FFPMs by ISO/DIN 1629 standard) are perfluoroelastomeric compounds containing an even higher amount of fluorine than FKM fluoroelastomers. They have improved resistance to high temperatures [1] [2] and chemicals and even withstand environments where Oxygen-Plasma are present for many hours ...

FFKM parts are used in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications. The long-term, proven performance of FFKM parts can mean less frequent seal changes, repairs and inspections, increasing process and equipment uptime for greater productivity and yield.

FKM is the ASTM designation for a class of fluorinated, carbon-based synthetic rubber, commonly known as fluoroelastomer. FKM was originally developed in the late 1950s in response to demand for high performance seals in the aerospace industry.

Oct 25, 2024 · FFKM (Perfluoroelastomer) is highly valued for its nearly universal chemical compatibility, exceptional resistance to high temperatures, and extended lifespan in aggressive environments. Often used for sealing in microfluidic components, FFKM is commonly used in industries such as petrochemistry, and aerospace due to its outstanding properties.

What is FFKM? FFKM, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM, resulting in higher temperature ratings (up to approximately 325°C/617°F) and improved chemical resistance with nearly universal chemical compatibility.

To combine the elastic properties of elastomer compounds with the excellent chemical and thermal resistance of PTFE, Parker has developed the Parofl uor® compound family (FFKM). Compared to conventional perfl uorinated elastomers, Parofl uor® of ers excellent.

Kalrez® perfluoroelastomer (FFKM) parts withstand attack from more than 1,800 chemicals, solvents and plasmas. The Kalrez® product line delivers outstanding performance in aggressive process environments.

Mar 10, 2025 · FFKM (Perfluoroelastomer) is a fully fluorinated elastomer (rubber) distinguished by its flexibility, elasticity, and exceptional resistance to aggressive chemicals and extreme temperatures. Unlike PTFE, FFKM can maintain a reliable seal …

Perfluoroelastomers (FFKM) are fully fluorinated fluorocarbon elastomers that fill a critical gap in applications involving aggressive chemicals at high temperatures, up to 325°C.

FFKMs exhibit better resistance to such environments versus other elastomers such as fluoroelastomer (FKM, e.g., DuPontTM Viton®, etc.) and silicone (MQ). Fig. 1 shows the effect of chemical and physical plasma attack (% weight loss) on different types of elastomeric materials.
