Additional Information

Fluorine rubber (FKM) is renowned for its exceptional resistance to harsh chemicals, fuels, and high temperatures. This makes it a critical material in demanding applications across various industries. FKM exhibits superior resistance to oils, fuels, and solvents, outperforming many other elastomers in these challenging environments. Additionally, its high heat resistance, typically reaching 260°C, allows it to function reliably in applications involving extreme temperatures.

FKM’s inherent flame retardancy and ozone resistance contribute to its use in fire-resistant materials and outdoor applications. Its abrasion resistance makes it suitable for seals and gaskets subjected to wear and tear. However, FKM can be more expensive than some other elastomers and requires specific compatibility considerations due to its unique chemical structure.
