Viton® Material Description

Viton® is a trade name for the Chemours brand of fluorocarbon, also known as FKM. As a high-performance rubber, Viton® is renowned for its exceptional resistance to a broad range of substances, including high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics, and many organic solvents and chemicals. Its performance varies by the level of fluorine content in the polymer, with an increase in fluorine improving fluid resistance but reducing low-temperature flexibility.

Viton® Variations

Viton® variations include Viton® A, Viton® B, Viton® F, Viton® GLT, Viton® GFLT, Viton® Extreme (ETP), High-Visibility Viton®, and Metal Detectable Viton®.

Standard Types of Viton® (A, B, F) are defined by their relative resistance to chemicals due to different levels of fluorine content. Viton® general type A has a 66% composition of fluorine, Viton® middle fluorine content type B has a 67-68.5% composition of fluorine, and the high fluorine content type F has a 70% composition of fluorine. Of these standard types, Viton® F demonstrates the best fluid resistance but reduced flexibility at low temperatures. On the other hand, Viton® A has the best flexibility at low temperatures and comparatively reduced fluid resistance.

Because of this tradeoff between chemical resistance and low-temperature flexibility, Viton® GLT and GFLT were created using copolymerized fluorinated vinyl ether monomer. This allows for Viton® GLT and GFLT to offer excellent chemical resistance while maintaining low-temperature flexibility.

Extreme Viton®, or Viton® ETP, exhibits the same chemical resistance as standard types of Viton® with additional resistance to acids, hydrocarbons, low molecular weight esters, ketones, aldehydes, and highly caustic solutions.

High-Visibility Viton® is recommended in applications that require o-rings to be highly visible (typically in downhole drilling). High-Visibility Yellow Viton® o-rings maintain properties identical to its original compound, with the addition of a distinguishable neon hue.

Metal Detectable Viton® allows for o-ring fragments as small as 2mm to be identified and extracted to ensure safety and compliance with FDA regulations. Viton® metal detectable o-rings retain the same qualities as the general Viton® o-ring compound.

Physical Property Difference Among Types/Families of Viton

Cure System

The curing system used to vulcanize the elastomer, also known as cross-linking, significantly affects the final physical property characteristics of the compound.

Bisphenol Cured (A, B, F): Offers fast cure rates, excellent scorch safety, and resistance to compression set.

Peroxide Cured (GLT, GFLT, ETP): Offers enhanced resistance to aggressive substances, including lubricating oils, steam, mineral and organic acids, and aggressive biodiesel. They have a similar hydrocarbon fluid resistance to polymers with the same fluorine content cured with bisphenol.
