FFKM Rubber Sleeve

FFKM rubber sheath is made of Perfluoroelastomer, which is a high-performance sheath specially designed for the protection and sealing of parts under extreme corrosion, high temperature and high purity. All hydrogen atoms in the molecular structure of the material are completely replaced by fluorine atoms, and the chemical stability is close to that of PTFE. At the same time, it has the flexibility and resilience of rubber. This product can effectively isolate medium corrosion, improve sealing life, and reduce downtime costs caused by frequent replacements.

Main characteristic

• Excellent Chemical Resistance: Resistant to almost all chemical media, including strong acids, strong alkalis, amines, esters, ketones, ethers, and strong oxidizers.
• Wide Temperature Range: Continuous operation from -40℃ to +325℃.
• Outstanding Elasticity and Flexibility: Maintains sealing resilience even under high temperature and strong corrosive environments.
• Low Permeability: Suitable for vacuum, ultra-pure gases, and applications requiring high sealing performance.
• Clean and Non-Extractable: Extremely low metal ion extraction, meeting high cleanliness standards for semiconductor and pharmaceutical industries.
• High Customizability: Can be tailored in size, wall thickness, and hardness according to specific requirements.

Typical application

• Chemical Equipment: Protective sheaths for pump shafts, agitator shafts, and pipeline joints against corrosion.
• Semiconductor Industry: Protection of key components in reaction chambers and gas delivery systems.
• Pharmaceutical & Food Engineering: Prevents disinfectants and solvents from corroding metal or plastic components.
• Aerospace: Protective and sealing sleeves for components in fuel and hydraulic systems.
