What is Viton 90?
Viton® 90 is a fluoroelastomer known for its excellent chemical resistance and ability to withstand high temperatures. Its AED rating makes it ideal for applications in aggressive environments, such as oil and gas exploration, where exposure to harsh chemicals like hydrogen sulfide (H₂S) and hydrocarbons is common. FKM, commonly referred to as Fluoroelastomer or FKM material, is a synthetic rubber prized for its exceptional performance in demanding applications. It is a preferred choice for FKM seal material and FKM Viton material, known for its robustness in various industrial uses.Viton® is a specific brand of Fluorocarbon (FKM) and is a registered trademark of The Chemours Company. This synthetic rubber polymer is commonly used in o-ring applications for aircraft engines, automotive fuel handling systems and other applications requiring high temperatures and low compression set.Viton is a versatile, inert alternative material for O-rings, gaskets, and other sealing components. The material is well-regarded for its resistance to chemical damage and its stability in high-temperature and high-pressure environments.
What is the alternative to Viton?
Viton alternatives like Buna-N, EPDM, and silicone rubber are commonly used in various industrial applications. Choosing the right one depends on the specific performance requirements. EPDM’s performance in low temperatures makes it a better choice over Viton in cold environments. Its exceptional resistance to water and steam (in any temperature) also makes it a better choice over Viton.EPDM and FKM are two popular rubber types. EPDM is best for weather, ozone, and water resistance, while FKM (Viton®) is ideal for fuel, oils, and high-temperature applications. EPDM vs FKM Rubber Comparison.The rubber with the highest tensile strength is generally Fluoroelastomer (FKM), also known as Viton. FKM rubber offers excellent resistance to heat, chemicals, and mechanical stress, making it ideal for high-performance applications.
What is the grade of Viton?
The standard grade for Viton™ is A grade, which has 66 percent fluorine content and is most commonly used in o rings and seals. Viton™ B offers better fluid resistance and Viton™ F is particularly good for resistance to fuel permeation. Both Viton and PTFE have their strengths, and which one is better depends on your specific application. Viton is excellent for flexible seals that need to resist oils and fuels, while PTFE is ideal for extreme chemical resistance and non-stick applications.Viton®/ FKM and NBR compounds have several very crucial differences that make them well-suited to certain applications. While both Viton/ FKM and NBR seals act as very good sealing options at moderate temperatures, Viton®/ FKM is far superior for high temperature applications.Black Fluorocarbon O ring, also known as a FKM o-ring or VITON, FPM orings. FKM (VITON ®) O’Rings have a low compression set and have high temperature and chemical resistance with Durometer / Shore A 90 which use for high pressure. For normal pressure you can use O-Ring FKM shore 75 .Viton is a brand of FKM fluoroelastomer rubber, a synthetic rubber and fluoropolymer elastomer commonly used in O-rings, chemical-resistant gloves, and other molded or extruded goods.
What are the disadvantages of Viton?
Disadvantages of Viton® Seals Performance-wise, Viton® isn’t ideal for every application. For instance, under excessively high temperatures (or fire), fluoroelastomers like Viton® decompose, often releasing hydrogen fluoride, which is toxic and associated with ongoing respiratory tract irritation. As mentioned, Viton is DuPont’s (now Chemours) brand name for fluorocarbon rubber. This is a synthetic rubber and fluoropolymer elastomer and is commonly used for O-rings and other molded or extruded parts.Viton is characterized by its: Resistance to degradation by a greater variety of fluids and chemicals than any nonfluorinated elastomer. Excellent resistance to oils, fuels, lubricants, and most mineral acids. Extremely low permeability to a broad range of substances, including oxygenated automotive fuels.
What is another name for Viton?
Fluoroelastomer, FKM, FPM, and Viton® are all different names for the same synthetic rubber material family. FKM is an abbreviation of Fluorkautschukmaterial (i. All FKMs contain vinylidene fluoride as the common monomer, to which different other monomers are added for specific types and functionalities, fitting the desired application.Disadvantages of FKM Higher cost than other non-fluorinated hydrocarbons. Not as chemically resistant as FFKM to chemicals but still excellent for most applications. Smaller temperature range than FFKMs but still better than other elastomers. Choosing the wrong FKM for an application can lead to rapid failure.
What is Viton used for?
Viton® is a specific brand of Fluorocarbon (FKM) and is a registered trademark of The Chemours Company. This synthetic rubber polymer is commonly used in o-ring applications for aircraft engines, automotive fuel handling systems and other applications requiring high temperatures and low compression set. Viton (FKM)®, known for its high heat resistance, can last over a decade in applications involving high temperatures. Silicone seals, popular for their flexibility and temperature resistance, can last over 10 years in the right conditions.
