What is the composition of Viton?

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 are the properties for Viton?

Viton® rubber properties

  • Excellent chemical resistance.
  • High density and high-quality feel.
  • Wide temperature range (-45°C – 204°C).
  • Excellent weatherability and ozone resistance.
  • Excellent gas and liquid permeation resistance.
  • Suitable for explosive decompression, CIP, SIP and FDA.

What are the different grades of Viton?

There are four major families of Viton™ fluoroelastomers: A, B, F, and ETP, each with its own unique performance characteristics.

How can you tell 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.

How do you test rubber material?

The most common method of determining the density of a rubber material is to weigh a test piece in air and water. Weighing in air provides the actual weight and weighing in water provides the volume. The density is then calculated by dividing the weight by the volume.

Is Viton chemical resistance?

Viton fluoroelastomer in general has a high temperature tolerance and chemical resistance rating. It is a synthetic rubber that resists many hydrocarbons, biodiesel, and petro chemicals, but is NOT compatible with ketones.

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 EPDM?

Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.

What is the difference between nitrile and Viton?

Which is better Viton or nitrile?

Environmental Properties: Viton® O-rings and seals have a wide range of chemical resistance (involving mineral acids, fuels, and oils) and this material is also highly resistant to oxidation, UV exposure, fungus, weather, ozone, and mould. This makes Viton® far superior to Nitrile in these regards.
