Are there different grades of Viton?

There are three major families of standard Viton fluoroelastomer: A, B, and F. The Viton A types are comprised of vinylidene fluoride (VF2) and hexafluoropropylene (HFP). The B and F types are made with vinylidene fluoride (VF2), hexafluoro- propylene (HFP), and tetrafluoroethylene (TFE).

What is difference between Viton and FKM?

FKM is the American standard ASTM short form name for Fluro-Elastomer. VITON™ is a registered trademark of Du Pont performance elastomers, the original developers of the rubber. However, the Viton is also used as a general name for the material, no matter who the manufacturer is.

What is Viton A material?

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.

Which is better Viton a or Viton B?

Viton® B offers superior resistance to both diluted and concentrated aggressive acids, and various mineral acids including: Sulfuric Acid, Nitric Acid, and Hydrochloric Acid. Viton® B offers better overall fluid resistance than Viton A, with economical pricing.

What are the different types of Viton rubber?

Viton fluoroelastomer products are designated as A, B, or F types according to their relative resistance to attack by fluids and chemicals.

What kind of resistance does Viton a have?

Viton A – General Properties Offers a broad range of resistance to oils, fuels, lubricants and most mineral oils. Very good resistance to many aliphatic hydrocarbon fluids that act as solvents for many other rubbers. Exceptionally good resistance even at temperatures that can stiffen other non-fluorinated elastomers.

What are the Viton B-type family products?

Viton™ B-type family products can be blended with other Viton™ fluoroelastomer types to modify viscosity, enhance processability, and improve flow. The product is offered in two grades: The “2” versus “6” is based on a measure of the polymer’s viscosity, which determines rubber processability.
