Fluorinated Polymer
Class of synthetic rubbers based on fluorocarbon molecules that provide high resistance to heat and chemicals. Products made from fkm are frequently found in fuel systems, aerospace engines and chemical processing plants. The material is classified by its fluorine content, which typically ranges from sixty six to seventy percent.
It bridges the performance gap between nitrile rubber and perfluoroelastomers.
Chemical Compatibility
Exceptional performance in petroleum based oils and fuels makes this polymer a standard for automotive and industrial sealing. It resists degradation from oxygenated fuels and many aggressive additives used in modern lubricants. Low permeability to gases and vapors further enhances its utility in containment systems.
Thermal Envelope
Functional stability is maintained at temperatures up to two hundred degrees Celsius for extended periods. Brief exposures to even higher heat are possible without immediate loss of mechanical properties. At the lower end of the scale, standard grades become stiff and lose their sealing effectiveness around minus twenty degrees Celsius.
Curing Variety
Differing vulcanization methods such as bisphenol or peroxide systems allow for tailored performance characteristics. A peroxide cured compound offers improved resistance to water and steam compared to its ionic counterparts. Proper selection of the cure type is required to match the seal to the specific fluid and temperature requirements of the application.
The final choice impacts both the longevity of the part and its resistance to compression set.
