What is FKM Rubber?
FKM rubber, also known as fluoroelastomers have become very popular for use in the automotive industry. This is due to their exceptional heat and chemical resistance, which makes the rubber perfectly suited to the transport of fuel, particularly bio-diesel. FKM rubber is often separated into different classes depending on either their chemical composition, their fluorine content or their crosslinking mechanism.
FKM rubber is highly resistant to high temperatures up to +250°C. However they aren’t as suited to cold temperatures as other rubber compounds, with -10°C being the minimum functioning temperature. Despite FKM sheeting having high resistance to hydrocarbons, oils, acids and chemicals, it cannot be used where resistance to ketones is required.
