FKM rubber sheet Q&A – The Common Questions about Fluoroelastomers

Throughout the extensive 30-year history of formulating and manufacturing rubber products for diverse applications, We have compiled a list of commonly encountered questions pertaining to Fluoroelastomers. Should you have any additional questions about rubber applications please contact us at [email protected].

FKM has a temperature range of -20°F to 500°F. However, specialty formulated grades can adjust this maximum or minimum range.

FKM exhibits excellent resistance to mineral oils, greases, fuels, hydraulic fluids, and aliphatic hydrocarbons. However, its resistance to acids and bases is poor to fair.

Yes, certain FKM compounds are mixed using FDA approved ingredients per 21 CFR 177.2600 for use in food processing applications where resistance to high temperatures and various chemicals is required.

Viton™ A has a better compression set, while Viton™ B exhibits greater chemical resistance and retains flexibility better after dry heat aging.

FKM rubber products have an expected shelf life of 20 years if stored properly in a cool, dry, and dark environment away from direct sunlight.

FKM provides superior chemical resistance compared to nitrile, neoprene, and silicone. While nitrile is less expensive and offers good resistance to petroleum-based oils and fuels, FKM has a wider temperature range and better chemical resistance. Neoprene is less resistant to heat and chemicals compared to FKM. Silicone has a higher flexibility but lower chemical resistance compared to FKM. EPDM is less resistant to hydrocarbons and high temperatures, when compared to FKM.

Fluoroelastomers offer exceptional chemical resistance and thermal stability, making them a preferred choice in various demanding industrial applications. Understanding the characteristics, applications, and limitations of FKM is crucial in selecting the right sealing solution for specific requirements. Whether it’s in aerospace, automotive, or chemical processing, FKM remains a reliable choice for sealing solutions.

Unlike many other rubber manufacturers that depend upon external laboratories, mixing and testing facilities, Our Company can develop compounds, mix materials, thoroughly test and process your rubber products in a single facility. Our wealth of experience in material design and engineering, unique manufacturing processes, and tight control over each step of production, are among the key contributors to how Beijing Rubber remains World Clients’ Choice.

Also Chinese Fluoroelastomers manufacturers had developed equivalent grades of  Fluoroelastomers as those big brands of world manufacturers like Chemours Viton™. These Chinese equivalent grades Fluoroelastomers rubber had been widely used in Chinese industries for over tens of years. The quality is very much proved by their performance in all industries. Further more, we also exported these  Fluoroelastomers rubber sheets of different grades to European countries and other continents since 2010. The quality of our Fluoroelastomers is surely reliable and the price is much acceptable. Please contact us for a quote.
