An Overview of Viton and Its Sealing Capabilities
25 March 2022Components of engines, assemblies, and other products must be installed properly and tightly so they remain functional for the rest of their service life. One way to ensure the proper assembly of the components is through maximising mechanical seals.
Mechanical seals like gaskets can fill the space between two or more surfaces, preventing any leak from developing. Most of the time, sealing with gaskets are preferred by many industries since permanent sealing processes like gluing and welding may fail to provide a leak-tight sealing. Mechanical sealing is also maximised in most industrial applications since it can meet most of their assembly requirements.
To date, mechanical seals can be made from a wide variety of materials. But one material that is often used for mechanical seals is Viton.
Primary Composition of Viton
Viton is a mixture of synthetic rubber and fluoropolymer elastomers that comes from DuPont, a reputable producer of chemicals and science-based products. This material has been used in creating rubber seals, gaskets, and O-rings. To date, Viton has four families of polymers.
- A (Dipolymers of VF2/HFP) – This type of Viton polymer is comprised of 66% fluorine, making it effective for general-purpose sealing of automotive and aerospace products.
- B (Terpolymers of VF2/HFP/TFE) – Maximises 66% fluorine content, this type of Viton polymer is significantly useful for chemical process plants, power utility seals, and gaskets.
- F (Terpolymers of VF2/HFP/TFE) – F family of Viton is comprised of 70% fluorine. It can be effective in oxygenated automotive fuels and concentrated aqueous inorganic acids.
- Specialty Types – Specialty types such as GLT, GBLT, GFLT, and Viton Extreme can all be useful for the automotive and oil exploration industries.
Viton’s Remarkable Benefits
Since Viton comes from a reputable producer, it can easily provide benefits to industries that use sealing products out of this material.
One of the benefits of Viton sealing products is they can withstand extreme temperatures. From significantly hot temperatures down to extremely low temperatures, Viton sealing products can effectively resist these conditions and continue to seal various assemblies. Another benefit of Viton sealing products is they can resist oil and chemicals. Despite being exposed to these elements, Viton seals, gaskets, and O-rings can operate continuously and avoid unnecessary leaks.
Other elements that Viton sealing products can withstand include atmospheric oxidation, ultraviolet rays, climatic conditions, mould, and fungus.
Some more benefits of Viton are low burning characteristics and reputable electrical properties.
Maximising Viton Products
Viton’s remarkable benefits have paved the way for its usage across industries. Some industries that use Viton are aerospace, automotive, manufacturing, and transportation industries. As for their exact applications, Viton mechanical seals such as gaskets and O-rings have been very useful for retaining the service life and functions of pumps, valves, and engine components.
