FEPM - Tetrafluoroethylene-Propylene Rubber

FEPM - Aflas® O-rings are sealing rings made from a special type of fluoroelastomer called Tetrafluoroethylene-Propylene Rubber (FEPM). FEPM combines the chemical resistance of fluoroelastomers with the elastic properties of ethylene-propylene rubber (EPDM). FEPM O-rings offer excellent resistance to acids, bases, solvents, and high temperatures, comparable to FKM (fluorocarbon) O-rings.

O-rings made from Tetrafluoroethylene-Propylene Rubber are particularly suitable for applications where FKM O-rings may not suffice due to more aggressive chemical environments. They are commonly used in the chemical processing industry, oil and gas industry, and automotive sector for sealing components exposed to aggressive chemicals. FEPM - Aflas® O-rings can also be used in the pharmaceutical industry due to their good chemical stability and inertness.

FEPM - AFLAS® O-rings

AFLAS® is a trade name for FEPM (Tetrafluoroethylene-Propylene) rubber produced by AGC Chemicals. FEPM - Aflas® O-rings offer excellent chemical resistance and thermal stability, comparable to other Tetrafluoroethylene-Propylene Rubber (FEPM) materials. They are particularly suitable for applications involving high temperatures, steam, and aggressive chemicals.

AFLAS O-rings are widely used in the oil and gas industry, chemical processing plants, and the automotive industry due to their durability and resistance to oils, fuels, and acids. The AFLAS series of FEPM rubber also exhibits good electrical insulation properties, making it suitable for electrical applications.

Advantages of FEPM O-rings

O-rings made from FEPM offer several advantages that make them suitable for demanding sealing applications. Firstly, FEPM O-rings have excellent chemical resistance, making them resistant to aggressive acids, bases, and solvents. This makes them ideal for use in the chemical processing industry and the oil and gas industry.

Additionally, FEPM - Aflas® O-rings offer a wide temperature range, typically from -10°C to 200°C, making them suitable for both low and high-temperature applications. FEPM O-rings also exhibit good mechanical properties, such as high tensile strength and tear resistance, ensuring durability in use.

In summary, the advantages of FEPM - Aflas® O-rings include excellent chemical resistance, wide temperature range, and strong mechanical properties, making them a reliable choice for critical sealing applications in various industries.

Applications of Tetrafluoroethylene-Propylene Rubber

FEPM - Aflas® O-rings find diverse applications in industrial sectors where high chemical resistance and thermal stability are required. They are widely used in the chemical processing industry for sealing pumps, valves, and pipes that come into contact with aggressive chemicals and solvents.

Additionally, FEPM seals are used in the oil and gas industry to seal components exposed to harsh environments and chemicals. In the automotive sector, they are used in engine components, fuel systems, and transmissions due to their resistance to oils and fuels.

FEPM - Aflas® O-rings are also applied in the pharmaceutical and medical industry due to their chemical stability and inertness. In short, FEPM O-rings are suitable for critical sealing applications where other materials may not meet the requirements of aggressive environments.

Disadvantages of FEPM O-rings

While Tetrafluoroethylene-Propylene O-rings offer many advantages, there are also some disadvantages to consider. One drawback is that FEPM O-rings are generally more expensive than standard rubber O-rings like NBR (nitrile rubber) or EPDM (ethylene-propylene rubber). This may increase the cost of sealing applications with FEPM - Aflas® O-rings.

Additionally, O-rings made from FEPM, despite their good chemical resistance, may not have the same broad resistance as FKM (fluorocarbon) O-rings against some aggressive chemicals. It is important to check the compatibility of FEPM - Aflas® O-rings with specific media before application.

Lastly, FEPM O-rings may be somewhat limited in available sizes and hardness compared to more common rubber types. This may affect their suitability for certain sealing applications.
