FFKM is one of the materials available for rubber seals. Perfluoroelastomer (FFKM) is a high-grade polymer with a fluoridated chemical composition that allo ws us to develop and produce FFKM ‘O' rings that are resistant to high temperatures, chemicals, and oxygen-plasma. We are a leading Perfluoroelastomer FFKM O-Rings manufacturers in India.
What is FFKM?
Tetrafluoroethylene (TFE), perfluoro methyl vinyl ether (PMVE), and cure site monomer (CSM) are the three monomers that make up FFKM. Perfluoroelastomer (FFKM) combines the elasticity and flexibility of FKM with the enhanced chemical resistance of polytetrafluoroethylene (PTFE). Its excellent chemical resistance is completely attributable to its chemical structure, which composes of super-strong carbon-fluorine bonds that provide our FFKM elastomer products with their great chemical, thermal, and oxidation resistance.
Uses of Perfluoroelastomer FFKM
FFKM seals can be utilized successfully in severe circumstances and there is no need for regular replacement due to these features. As a result, maintenance expenses might be reduced significantly. Therefore, FFKM seals are used mostly in oil refineries, chemical process industries, aircraft, semiconductor industries, pharmaceutical industries, and vacuum industries.
Features of Perfluoroelastomer FFKM O-Rings:
We can produce FFKM ‘O' rings with the following characteristics:
- Best in class chemical resistance
- Excellent gas and liquid permeation resistance
- Excellent weather and ozone resistance
- Good mechanical properties
- Exceptional sealing performance
- Self-extinguishing and non-flammable in air
Disadvantages of Perfluoroelastomer FFKM O-rings
FFKM is not appropriate for every application. For instance, this material does not perform best at low temperatures.
Advantages of Perfluoroelastomer FFKM O-rings
The combination of strong chemical resistance and a wide temperature range. The permeability is minimal, and the material has low outgassing values, especially at temperatures exceeding 200 degrees C. As a result, this makes it excellent for vacuum applications, particularly in the Semiconductor sector. In contrast to silicone seals, the sealing effect also lasts a long period over the whole temperature range.
