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 the difference between Viton and FKM?

All in a name

Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same.

Is Viton an FKM or FFKM?

Both materials are well suited for use in the -15 to 205°C range. FKM has an advantage in lower temperatures and FFKM has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart.

What is another name for Viton?

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.

What is Viton FKM?

FKM (FPM, Viton^®, Fluorel^®) resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, diesel fuels, silicone oils and greases. It is suitable for high vacuum applications.

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

Is FKM and FPM the same?

So what's the difference between FPM and FKM? FPM is the international designation to ISO – whereas FKM is the ASTM abbreviation. Both of these designations stand for the same base material : Fluoro Rubber.

What kind 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.

What is FKM full form?

Fluoroelastomers or Fluorocarbons (FKM), also known as Viton^®, are highly fluorinated polymers that are suitable for continuous use at elevated temperatures. Various grades are available, including copolymer and terpolymers.

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.

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 fluorocarbon the same as FKM?

Fluorocarbon (or Viton® as it's is more commonly known) is a brand name of DuPont. In situations where both temperatures and the surrounding conditions can be extreme, Fluorocarbon offers excellent performance.

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 reach compliant?

J-Flex FKM/ Viton™ is safe to work with: independent tests confirm compliance to the latest REACH SVHC Candidate List.

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 NBR?

Standard Viton® / FKM vs Standard Nitrile

Standard Viton®/FKM compounds can provide continuous sealing at temperatures up to approximately +205°C. Standard NBR on the other hand is only effective for continuous sealing at temperatures up to +110°C (with short term sealing at 130°C.)

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.

Are there different types of Viton?

There are four major families of Viton™ fluoroelastomers: A, B, F, and ETP, each with its own unique performance characteristics. A major differentiator between the Viton™ product families is fluid resistance, which is based on the polymer's fluorine level.

Is Viton better than silicone?

Both materials are well suited for use in the -30 to 205°C range. Silicone has an advantage in lower temperatures and Silicone has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart.

What is Viton elastomer?

Viton™ is a fluoropolymer elastomer and synthetic rubber compound, trademarked by DuPont under this brand name. It's a fluorinated hydrocarbon rubber product with amazing capabilities, designed to withstand even the most challenging of environments.

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.

What polymer is Viton?

What 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 FKM the same as PTFE?

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.

Which is better Viton or PTFE?

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 durometer is Viton?

Viton is vulnerable to low molecular organic acids, ammonia gas, alkalis, amines, glycol-based brake fluids, and super-heated steam. The durometer hardness of this Viton O-ring is 90A. Durometers measure the hardness of a material and its resistance to permanent indentation.

What is the difference between FKM and FFKM?

The key difference between FKM and FFKM is that FKM offers a less degree of versatility compared to that of FFKM. FFKM can withstand comparatively high temperatures than FKM. Moreover, FKM is more resistant to burning than non-fluorinated hydrocarbon compounds while FFKM is self-extinguishing and non-flammable in air.
