Who makes 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 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 the difference between Viton and Viton A?

Although Viton® A has higher thermal stability than Viton® B, it is typically used in applications where high surface pressures or low temperatures are present.

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.

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.

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

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.

Is NBR the same as Viton?

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 Viton and FKM the same?

Viton® is a trademark of a synthetic rubber and fluoropolymer elastomer commonly used in the manufacture of O-Rings. The name is a trademark registered by The Chemours Company and its international abbreviation is FPM (DIN/ISO denomination) or FKM (ASTM).

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.

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.

Are green O-rings Viton?

Viton®/FKM O-Rings (Fluorocarbon) Green.

Which is better Viton or Buna?

Viton is the choice over Buna for high-temperature applications. Viton seals hold indefinitely at temperatures up to 400°F and can last up to 48 hours at temperatures up to 600°F. Buna is effective to 250°F. However, it can effectively seal mechanical objects at low temperatures to –22°F.

What is Viton made out of?

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 better than FKM?

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.

What temperature can Viton withstand?

Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more than 48 hours.

How can you tell Buna from Viton?

Buna N is oil and solvent resistant. Viton has high-temperature resistance and chemical resistance. Buna N has a temperature resistance up to about 120 °C. Viton has a temperature resistance up to about 300 °C.

Is Viton electrically conductive?

Electrically conductive; relatively expensive; low resilience, poor low temperature flexibility.

Is fluorocarbon the 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 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.

Is Viton better than Hnbr?

HNBR has excellent abrasion resistance, making it a viable alternative to Viton® FKM. HNBR also has better low temperature properties and tear resistance than fluorocarbon.

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.

Why are some O-rings green?

Green o rings are hydrogenated Nitrile, also known as highly saturated Nitrile, or more commonly known as HNBR. These o rings have the green colour moulded into their rubber and were introduced with the refrigerant of 134a, suitable for high temperatures and fluctuating stress loads.

Is Viton good for diesel?

From its introduction in 1957, Viton has a long-proven resistance to a wide range of solvents and fuels. Since the mid 1990s, manufacturers have specified Viton for seals and gaskets for use in diesel fuel injectors because of its resistance to biodiesel fuels.
