FKM rubber, also known as fluoroelastomer rubber or Viton, is a synthetic rubber compound that exhibits exceptional resistance to heat, chemicals, and fuels. It is commonly used in industrial applications where high temperature and chemical resistance are critical requirements.
FKM / Viton rubber was first developed in the 1950s by DuPont as a high-performance elastomer for the aerospace industry. Since then, it has found widespread use in various industries, including automotive, chemical processing, oil and gas, and semiconductor manufacturing.
One of the primary advantages of FKM / Viton rubber is its ability to withstand high temperatures. It has a maximum continuous operating temperature of 250°C and can withstand intermittent temperatures of up to 300°C. This property makes it an ideal material for high-temperature applications such as engine seals, gaskets, and O-rings.
FKM / Viton rubber also exhibits excellent chemical resistance to a wide range of chemicals, including acids, bases, solvents, and fuels. It can withstand prolonged exposure to many harsh chemicals without degrading, making it suitable for use in chemical processing equipment, fuel systems, and oil and gas exploration.
Another advantage of FKM / Viton rubber is its exceptional sealing properties. It is highly resistant to compression set, meaning that it can maintain its seal even when subjected to high pressure and temperature fluctuations. This property makes it an ideal material for O-rings, gaskets, and other sealing applications.
Despite its many advantages, FKM / Viton rubber is relatively expensive compared to other elastomers. However, its superior performance and durability make it a cost-effective choice for many applications that require high-temperature and chemical resistance.
In summary, FKM / Viton rubber is a versatile elastomer that exhibits exceptional heat and chemical resistance, making it an ideal material for use in a wide range of industrial applications. Its ability to maintain its seal even under high pressure and temperature fluctuations makes it a reliable choice for sealing applications. While it may be more expensive than other elastomers, its superior performance and durability make it a cost-effective choice for many applications.
