Fluorine rubber
What is Viton Rubber?
Fluoroelastomer is a special fluoroelastomer polymer (FKM), which was introduced to the aerospace industry in 1957 to meet its demand for high-performance elastomers. After the introduction, the use of this material quickly spread to other industries. Today, fluorine rubber seals, o-rings and other rubber parts are now often used in the automotive, electrical, chemical and fluid power industries due to their natural resistance to fuels and oils.
In addition to fuel and oil resistance, fluororubber gaskets and other parts have a reputation as a high-performance elastomer that can work in very hot and corrosive environments. These features make Viton a natural choice for parts that need to succeed in harsh environments.

Features and advantages of fluorine rubber
Fuel and oil compatibility.
Compatibility with many other chemicals, including vegetable oils, alcohols, dilute acids, etc.
It can be operated continuously at 204°C, even after a short time shift to 315°C.
Certain grades of fluororubber perform the same function at temperatures as low as -40°C.
Complies with strict environmental regulations in terms of emissions, leaks and leaks, especially compared to some other elastomers.
