FE2605 FKM China 3F which is 66.5% compression molding and extrusion copolymer Fluoroelastomer 

FE2605 is a copolymer of vinylidene fluoride and hexafluoropropylene. FE2605 is a gum of low viscosity, the fluorine content of which is 66.5%. It is mainly used in the processing of extrusion, transfer molding and injection molding.

Fluoroelastomer (FKM), a special type of fluoroelastomer, exhibits excellent heat resistance, chemical stability, and flame resistance, making it widely utilized in applications requiring high-temperature sealing and chemical corrosion resistance.

Here are the performance, characteristics, and applications of FKM:

Heat Resistance: FKM can operate long-term in high-temperature environments, typically withstanding temperatures up to 200°C or higher. This property finds extensive use in automotive engines, aerospace, and industrial equipment.

Chemical Stability: FKM demonstrates outstanding chemical stability, resisting corrosion from various chemicals and solvents. It is suitable for sealing components and fluid transfer systems that require corrosion resistance.

Flame Resistance: FKM exhibits good flame retardancy, maintaining structural integrity even under flame exposure, enhancing its applications in aerospace and automotive industries.

Mechanical Properties: FKM offers good mechanical strength and wear resistance, ensuring long-term sealing performance and elasticity.

Applications: Primarily used in automotive industry (e.g., automotive engine seals, fuel systems), aerospace (e.g., aircraft seals, spacecraft seals), chemical processing equipment (e.g., valve seals, pipe joints), and medical devices.

In summary, FKM, renowned for its excellent heat resistance, chemical stability, and flame resistance, is indispensable in many industrial sectors, providing reliable solutions for applications in extreme environments.
