The terms FKM, FPM and Viton® are all different designations that stand for the same base material, which is fluoro rubber.

What is another name for 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.

What is FPM seal material?

Fluorocarbon is an elastomers based on fluororubber (FPM, FKM), also known as VITON (registered trade name of Du Pont), which can be used for U-cups, lip seals, packings, wipers and special seals. Its outstanding properties include high resistance to heat, ozone, many chemicals and it is all-weather-proof.

What is a FPM O ring?

FPM-Viton® O-Rings are sealing rings for high temperature applications and/or in contact with agressive chemical products. Among the whole synthetic rubbers, FPM-Viton® is the most resistant to halifatic, aromatic and chlorinated hydrocarbons.

Is FKM and Viton the same thing?

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

Is FKM an FPM?

The terms FKM, FPM and Viton® are all different designations that stand for the same base material, which is fluoro rubber. FKM is the abbreviation according to the ASTM, FPM is the short form for the fluoroelastomer category according to DIN/ISO and Viton® is the registered trademark of DuPont Performance Elastomers.

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 FPM polymer?

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 FPM?

FPM is often used in high-temperature applications due to its excellent heat resistance and oxidative stability, whereas EPDM is employed when low temperature leak tightness is required.

Which is better VITON or EPDM?

Temperature - Viton® temperature resistance ranges from -20^°C to 210^°C, while EPDM temperature resistance ranges from -45^°C to 145^° This means that both are excellent for extreme temperatures, but EPDM has a slight edge in colder temperatures, while Viton® is better for heat resistance at higher temperatures.

What is the difference between nitrile and Viton?

The key difference between nitrile and Viton is that nitrile rubber compounds have comparatively a low density while Viton has comparatively a large density. However, by looking at the material, we can identify Viton by its appearance of green-brown colour where nitrile rubber has a yellow colour.

Is fluorocarbon same as Viton?

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.

Is FPM food Safe?

Viton® is often referred to as a material, but is actually a brand name of a fluoroelastomer. Qseals can supply Viton O-rings with EC1935/2004 certification. These O-rings are therefore fully food-grade and FDA approved.

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 PTFE and Viton same?

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 A and B?

Viton® B has better resistance and retains flexibility better after dry heat aging than Viton® A. It is recommended with good mechanical properties. Viton® B is specified by the Fluid Sealing Association to resist sulfur dioxide in power generating factory systems.

What is a Viton seal used for?

A Viton™ seal is simply a seal manufactured from Viton™. These seals or gaskets are commonly used to seal leaks, valves, pumps and similar. Viton™ o rings are the most common type of seal, which we provide here at NES in a variety of sizes and profiles.

Is FKM better than EPDM?

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.

What is a Viton seat?

Because of its heat tolerance and resistance to corrosion, VITON is used in the manufacture of valve seats such as a knife gate valve. However, this valve is not compatible with processes that involve water or steam.

What is the difference between FKM and Viton material?

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 vulcanized rubber?

Standard materials we vulcanize include Buna (Nitrile), Viton® (FKM), Aflas, Neoprene, EPDM, Neo/EPDM Blend, Silicone, and Fluorosilicone.

What FKM stand for?

FKM is the ASTM designation for a class of fluorinated, carbon-based synthetic rubber, commonly known as fluoroelastomer.

Is Viton plastic or rubber?

Viton is a synthetic, floronated hydrocarbon (fluorocarbon) rubber product produced and trademarked by DuPont Performance Elastomers (Viton refers to all types of DuPont fluoro-rubbers). Different kinds of fluoroelastomers possess different swell behaviors, and their processing / compression set resistance.

What Viton 75?

Description. 75 Durometer DuPont Viton® Fluoroelastomer (FKM) offers excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F.

What color are Viton gaskets?

Gaskets made of Viton® can be die cut from solid, sponge, or foam rubber. Durometers typically range from 60 to 90 (Shore A). Most gaskets made of Viton® are black, white, or brown in color; however, custom compounding can create specialized colors.
