FKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418, and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. All FKMs contain vinylidene fluoride as a monomer.

Is FKM a fluorocarbon?

Fluorocarbon elastomers are highly fluorinated, carbon backboned polymers used in applications to resist harsh chemical and ozone attack with a thermal stability to 500°F (262°C).

Is fluorocarbon FKM Viton?

Viton^® by ERIKS

Viton^® is the brand name for fluorocarbon rubber polymers of the Chemours Company. This type of polymer is used extensively by ERIKS, however we do not claim or promote the use of any specific brands of polymers in our compounds.

What type of material is FKM?

FKM is the ASTM designation for a class of fluorinated, carbon-based synthetic rubber, commonly known as fluoroelastomer. FKM has impressive heat resistance, allowing FKM seals to withstand temperatures greater than 200°C.

Is FKM and PTFE same?

FKM offers greater temperature resistance but falls short of PTFE's properties in terms of chemical resistance. While PTFE is slightly less thermally resistant but offers much in the way of non-adhesive properties.

What is FKM/Viton/Fluoroelastomer? Things you must know about FKM/Fluoroelastomer/Viton?

Is FKM and Viton the same?

These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.

What is FKM short for?

FKM is the American standard ASTM short form name for Fluro-Elastomer. It is the designation for around 80% of Fluoro-Elastomers defined by ASTM D1418. VITON™ is a registered trademark of Du Pont performance elastomers, the original developers of the rubber.

Is fluorocarbon the same as fluoroelastomer?

Fluoroelastomers also known as fluorocarbon compounds are used in a wide variety of high performance applications.

Is FKM plastic or rubber?

Unsourced material may be challenged and removed. FKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418, and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. All FKMs contain vinylidene fluoride as a monomer.

Is FKM rubber vulcanized?

If you compare FKM and vulcanized rubber, FKM is like the superhero, synthesized cousin to the latter. Vulcanized rubber is made by mixing natural rubber with additives (such as sulfur) in the process called vulcanization, which makes the material stronger and more flexible.

What is fluorocarbon polymer?

Fluorocarbon polymers are addition-reacted polymers that are fully or partially fluorinated along the carbon backbone. Polytetrafluoroethylene, commonly known as Teflon®, is a fully fluorinated form with a chemical formulation –(CF₂–CF₂)–.

Is FPM the same as FKM?

FPM is the ISO designation, FKM is the ASTM designation. Viton®, Dai-El and Technoflon are brands for FPM polymers. All of the designations stand for one single base material, which is fluoro rubber. This rubber is used in applications that need O-rings that are resistant to high temperatures and chemical attacks.

What is the difference between EPDM and FKM?

EPDM (EP, EPR, Ethylene-Propylene Rubber) Both materials are well suited for use in the -30 to 150°C range. FKM has an advantage in lower temperatures and EPDM has an advantage in higher temperatures.

Is FKM a silicone?

TYM Seals & Gaskets

TYM has nearly 40 years experience in supplying and manufacturing gaskets and seals made from silicone, FKM fluoroelastomer, neoprene, nitrile and more.

Is FKM reach compliant?

Solvay's Tecnoflon® FKM grades are REACH-compliant and select grades have been submitted for ISO 10993 biocompatibility testing.

Is fluorocarbon a thermoplastic?

Fluoropolymers may be mechanically characterized as thermosets or thermoplastics. Fluoropolymers can be homopolymers or Copolymer.

What is FKM rubber used for?

FKM is of high value in use as a class of synthetic rubber which provides extraordinary levels of resistance to chemicals, oil and heat. This type of rubber can be fabricated into seals, o-rings, and hoses for a variety of high performance applications in the automotive, aerospace, and petrochemical industries.

Is FKM FDA approved?

Known more commonly by its trade name of Viton™, fluorocarbons or FKM are high performance FDA approved silicone materials. They cope well with high temperatures, are chemically resistance and do not absorb water.

What is the difference between FKM and FFKM?

So, what is the difference between FFKM vs FKM ? Realistically, FFKM offers a greater degree of versatility than FKM. It's more chemically resistant and can withstand a greater range of operating temperatures, offering peak service temperatures of up to 330°C.

What is an FKM gasket?

FKM rubber gaskets are made of fluoroelastomer, a synthetic rubber that is known for its hard wearing properties. The material is used for O-rings, seals, gloves and most importantly for this blog post, FKM is used for gaskets.

Is fluorocarbon a rubber?

Fluorocarbon rubber is the best; polyacrylate, urethane and polyurethane rubber have poor acid resistance. 12. Oil resistance. Polyacrylate butyronitrile, urethane and fluorocarbon rubber have very good oil resistance; natural rubber, butylbenzene and allyl ethylene rubber are not oil resistant.

What material is Viton?

Viton® is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-rings and other moulded or extruded products.

Is Viton the same as Teflon?

Viton vs Teflon (PTFE) - Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.

What is the difference between Viton and EPDM?

Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.
