FKM Rubber Performance

Fluoroelastomers or fluorocarbons (FKM), also known as Viton, are highly fluorinated polymers suitable for continuous use at elevated temperatures.

Fluoroelastomer has an excellent heat resistance and flame retardancy and has excellent resistance to aging, ozone, antioxidant, oil, and a variety of chemical substances. They also have low gas permeability and a low compression set. However, they usually have only limited low-temperature capabilities. Although there are some special lower temperature grades to choose from. They also have limited resistance to steam, hot water, and (very) polar fluids (such as strong organic acids (such as formic acid), methanol, ketones, ammonia, and certain amines), while the new peroxide-cured grades are chemically resistant. Receptivity has improved. In addition, they are expensive, so they are only used when the components must withstand a particularly harsh environment.
