What is Viton?

Viton is a registered trademark of DuPont in manufacturing synthetic rubber and fluoropolymer elastic O-rings, seals, and gaskets. These elastomers are made up of copolymers of tetrafluoroethylene (TFE), hexafluoropropylene (HFP), and vinylidene fluoride (VDF).

There are four types of Viton polymers, and their fluorine content ranges from 66-70%. The main types are:

  • Viton A: Dipolymers of VDF and HFP, with a fluorine content of 66%.
  • Viton B: Terpolymers of VDF, HFP, and TFE, containing 68% fluorine.
  • Viton F: Terpolymers of VDF, HFP, and TFE, containing 70% fluorine are used in automotive fuels.
  • Viton speciality: Used in automotive and oil exploration.

Benefits of Viton

Unlike other elastomers, Viton can resist high temperatures while retaining its mechanical properties. Viton seals provide work even at temperatures of 400°F and offer incredible sealing for 48 hours at temperatures up to 600°F. They are resistant to oil and chemicals that are not affected by rising temperatures. It provides the best fluid resistance of any commercially available rubber.

Viton exhibits good resistance against compression while other non-fluorinated polymers become brittle at high temperatures. It is substantially resistant to atmospheric oxidation, sun, harsh climatic conditions, fungi, and mould.

Viton shows excellent electrical properties in low-voltage, low-frequency appliances, and exhibits low-burning characteristics.

Viton vs. Buna Seals

Both Viton and Buna provide good sealing support at a wide range of temperatures and are resistant to oils and lubricants. But there are some critical differences between the two.

  • Viton is much superior to Buna when it comes to high temperatures. While Viton can withstand temperatures up to 600°F, Buna can only resist up to 250°F.
  • Viton provides excellent resistance against a wide range of chemicals including oils, fuels, and mineral acids. These seals are also resistant to oxidation, UV exposure, ozone, fungus and mould. Buna is much less resistant and suffers degradation under ozone and harsh weather conditions.

Viton vs. Teflon

We at Helix Engineering, the most reliable name among Viton seal manufacturers in Texas, strongly recommend Viton seals over Teflon because :

  • Viton offers a much higher temperature resistance than Teflon which shows resilience up to 400°F.
  • Viton offers more elasticity and higher-quality sealing capacity than Teflon which is comparatively rigid.

Applications of Viton Rubber

Viton seals, O-rings, and gaskets manufactured in Helix are of the best quality for automotive and other transportation fuels. As we have said earlier, Viton has several grades according to its fluorine content. Type B and F have proven to be more compatible with acidic biodiesel as this fuel is unstable and oxidizing. Therefore, it is important to understand the requirements of the appliance and choose the right grade of Viton.
