It resists corrosion from a greater variety of fluids and chemicals than any non-fluorinated elastomer. It is 100% compatible with B100 (100% biodiesel). Viton, contrastingly, is a well-known fluoroelastomer that is used for highly corrosive or abrasive applications that are too harsh for synthetic rubbers. The most common compounds are Viton A, Viton B, Viton F, Viton B70, Viton GLT, Viton GFLT and Viton ETP. Whilst this is more expensive than standard compounds it is a lot cheaper than FFKM and can compete with some of these polymers in specific chemical exposure applications. To ensure the highest quality fluoroelastomer available, insist on products made only with Chemours Viton®. Viton® O-Ring and seal performance cost benefit makes it the second most popular sealing material. The 1/8" ID hose is perfect for the injector return lines on many … 4, July 2010 .

Rubber Chemical Resistance. Key Use(s): Fluorocarbon seals are ideal for aircraft engines, automotive fuel handling systems.Fluorocarbon is also good for high temperature / low compression set applications. $ 148.00 - $ 187.00USD / Pair of 1. However, there is much less information available on the compatibility of fuel system elastomers with biodiesel fuels. Chemical Behaviour Ratings for Plastic Chemical Resistant Fluoroelastomer Foam Strips Similar to Silicone, Fluoroelastomer withstands high temperatures and is superior material for oil and chemical resistance. Key Difference – Buna N vs Viton Buna N and Viton are commercial names for butadiene-acrylonitrile (nitrile rubber) and vinylidene fluoride-hexafluoropropylene copolymer, respectively.Both these elastomers are widely used synthetic elastomers that possess a unique set of physical and chemical properties. *The information contained in the chemical compatibility guide is believed to be correct. A – Recommended B – Minor to Moderate Effect C – Moderate to Severe Effect D – Not Recommended * Insuffient Data. Viton: Viton (fluorocarbon) o-rings offer a wide spectrum of chemical compatibility and temperature-range adaptability. FKM is the ASTM designation for a class of fluorinated, carbon-based synthetic rubber, commonly known as fluoroelastomer. * View chart. Kalrez® Parts Chemical Resistance. When it comes to chemical resistance, Viton can't be beat. The CRG details the performance of 20 elastomers with more than 1,000 individual chemicals, each at variety of room temperatures. You can refer to this chemical compatibility chart to verify the effects that over 600 different chemicals have on Silicone, EPDM, Viton®, Neoprene, Nitrile, Hypalon and Natural Rubber. Elastomer chemical compatibility Elastomer Seal Selection Criteria 3 8 30 Novotema is a world-class designer and manufacturer of technical components and elastomer sealing solutions for demanding applications.

Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment. The material is identified as "Viton®" in the database. Viton Extreme sealing elements exhibit excellent resistance to steam and to attack by an exceptionally broad variety of chemicals and fluids. Chemical Resistant Fluoroelastomer Foam Strips Similar to Silicone, Fluoroelastomer withstands high temperatures and is superior material for oil and chemical resistance. However, in the HVAC&R application, Viton is inherently incompatible with refrigerants because they are both fluorine containing compounds. Effects of incompatibility depend on the form of chemical attack and the temperature at which effects occur. Viton is a fluoropolymer that is typically known for its chemical resistance. Although nitrile rubber is resistant to chemical attack by ethanol, it is highly permeable to it. Fluoroelastomer (Viton®, FKM) offers a wide range of resistance to chemicals, oil and heat, with situational service life above 200°C. So we naturally get a lot of request for information about DI material compatibility. The most significant differences in compounds is the percentage of fluorine content and the curing system used to cure the Viton into its stable shape. Because Viton® is an established industry standard, many people incorrectly refer to any and all fluoroelastomers as Viton®. The effect of the refrigerant breaking down the fluoropolymer can be seen in the results from the Viton exposure charts below *Please contact service@usasealing.com or call 1-844-365-7315 to learn about pricing and purchase minimums* Viton™ Extreme™ ETP-600S is a copolymer of ethylene, tetrafluoroethylene (TFE), and perfluoromethylvinyl ether (PMVE). The range of chemicals to which Viton fluoro-elastomer is resistant is one of the broadest in the industry. EPDM is extremely resistant to many chemicals such as Acetaldehyde, Acetamide, and Ammonia. the use Of vulcanizates Of Viton* fluoroelastomer in the formulation of rubber articles intended for use in repeated food contact applications (21 CFR 177.2600). Our Grade A High Temperature Fluoroelastomer Hose (same material used in Viton hose) is intended for biodiesel applications, but can be used in many other various applications. Viton/butyl gloves are highly impermeable to many strong organic solvents that would destroy or permeate commonly used gloves (such as those made with nitriles ). Description: Combining high temperature resistance with outstanding chemical resistance, Fluorocarbon (also known as Fluoroelastomer) based compounds approach the ideal for a universal O-ring material. Viton ® o-rings from Marco Rubber offer excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F. They can solve the most challenging chemical applications in the pharmaceutical and bio-technology industries. Viton ® rubber, a specific fluoroelastomer polymer (FPM), was introduced into the aerospace industry in 1957 to fulfill its needs for a high-performance elastomer.
