Perfluoroether rubber FFKM

Perfluoroether rubber (FFKM) is a high-performance specialty elastomer material composed of perfluorinated vinyl ether copolymers. As one of the elastomer materials with the highest chemical stability, FFKM maintains excellent physical properties and chemical stability even in extreme environments, making it an ideal sealing material for high-end fields such as aerospace, semiconductor manufacturing, and petrochemical equipment; 

 1. Excellent chemical stability The molecular structure of FFKM contains no C-H bonds and is entirely composed of C-F bonds, making it highly resistant to almost all chemicals. The product can withstand the erosion of more than 1,600 chemicals, including strong acids, strong alkalis, organic solvents, oxidants, etc; 

 2. Wide operating temperature range Minimum operating temperature: -25℃ Maximum operating temperature: 327℃ It can maintain good elasticity and sealing performance even under extreme temperature conditions; 

 3. Excellent high temperature resistance It remains undeformed and unhardened after long-term use at a high temperature of 300℃, and can withstand an extreme temperature of 327℃ for a short period of time; 

 4. Low gas permeability With a tightly packed molecular structure, it exhibits extremely low permeability to gases and vapors, making it particularly suitable for applications requiring vacuum and high purity.
