Peroxide curing is the most common method for FFKM formulations. It uses organic peroxides to initiate a free-radical reaction, leading to the formation of crosslinks between polymer chains.

Jun 12, 2025 · When it comes to high-performance sealing materials, two names often come up: Fluororubber (FKM) and Perfluoroether Rubber (FFKM). While both are part of the …

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 …

FFKM parts are used in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications.

2 days ago · Perfluoroelastomers (FFKM) are a critical sealing solution for applications where reliability, longevity, and performance are non-negotiable.

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 …

When it comes to high-performance sealing solutions, two elastomers stand out: FKM (Fluoroelastomer, commonly known as Viton®) and FFKM (Perfluoroelastomer, known by …

What is FFKM? FFKM (Perfluoroelastomer) is a fully fluorinated elastomer where all hydrogen atoms are replaced by fluorine, resulting in extraordinary chemical stability and resistance to …

Jun 30, 2025 · FFKM stands for perfluoroelastomer, a synthetic rubber with remarkable properties. This ffkm material combines the flexibility of traditional elastomers with chemical …

In the 1970s, DuPont™ introduced Kalrez®, a perfluoroelastomer or FFKM compound, as the gold standard elastomer for high-performance seals in aggressive media environments. FFKM …
