Fluoro Rubber (Fluoro Rubber / FKM / FPM / Viton®) is a **fully synthetic polymer elastomer** with excellent **high temperature resistance, oil resistance, chemical corrosion resistance, fuel resistance and aging resistance**. FKM is widely used for sealing and protection in harsh environments, especially in environments in contact with petrochemical solvents, strong acids and alkalis, and fuel oil.
grade | Fluorine content(%) | Feature overview | Applicable industries |
General FKM | about 66% | Standard Viton rubber with good heat and oil resistance | Automotive, machinery, industrial seals |
High fluorine FKM | 67–70% | Improved chemical stability and corrosion resistance, suitable for moderate chemical environments | Chemical equipment, vacuum machinery |
Perfluorinated FFKM | More than 70% | Extremely chemical-resistant, high-temperature resistant, ultra-low pollution, suitable for use in the harshest environments | Semiconductor manufacturing, aerospace, medical equipment |
High fluorine FKM is a fluorine rubber material with a fluorine content of 67 to 70% in the original rubber. Compared with the general grade, it provides better chemical resistance and high temperature stability.
Material properties:
*Extremely high corrosion resistance**: Resistant to strong acids, strong alkali, organic solvents, oxidants, etc.
*Excellent high temperature resistance**: It can withstand temperatures above 250°C for a long time.
*Good electrical insulation**: used in high-frequency equipment and power industry.
*Anti-pollution, low surface energy**: Not easy to absorb pollution sources and easy to clean.
Application industries:
*Petrochemical equipment sealing
*Sealing rings for high temperature chemical reactors
* Semiconductor wafer process peripherals
* Food grade equipment contact parts (need to comply with FDA)
Perfluoroelastomer FFKM original rubber contains more than 70% fluorine. It is one of the most chemically resistant rubber materials on the market and is suitable for use in extreme environments.
Material properties:
*Ultimate chemical resistance: can be exposed to various types of strong corrosive media for a long time.
*Ultra high heat resistance: thermal stability up to 300°C.
*Excellent electrical insulation and air tightness**: Suitable for high voltage and vacuum systems.
*Non-toxic, low pollution: very suitable for high-cleaning industries such as semiconductors and biomedicine.
Application industries:
* Semiconductor vacuum chamber sealing
* Sealing components for liquid crystal manufacturing equipment
* Biomedical grade suction/diversion O-ring
* High-end petrochemical plant reactor system
