What is Viton™?
Viton™ rubber is a high-performance fluoroelastomer primarily engineered for use in extreme environments, resisting harsh temperature fluctuations and extreme chemical exposure. Its strength and lasting performance make it a popular option for many different uses.
Viton™ is a brand of synthetic rubber known as fluoroelastomer, developed in the 1950’s by DuPont. Viton™, though a trademarked name and product, has become the generic, recognisable term to represent this type of fluoroelastomer.
Brief History of Viton™
1957 – Viton™ was introduced by DuPont as one of the first fluoroelastomers, primarily for the Aerospace Industry to handle high temperatures and chemical exposure.
1960-70s – Expanded into the Automotive and Chemical Processing Industries.
1980-1990s – Specialised grades of Viton™ were introduced to tailor for low-temperature flexibility, food-grade applications and enhanced chemical resistance.
– Expanded into further industries including Oil & Gas and Pharmaceuticals
2015 – DuPont ‘Spun-off’ into the Chemours, where Viton™ continues to be manufactured today as a separate company.
Why use Viton™?
Viton™ is a widely preferred option among rubber seals, and there are several key reasons behind its popularity:
- Heat Resistance
– Withstands continuous temperatures up to 200–250°C (392–482°F)
– Outperforms most other rubbers, including Nitrile or EPDM, in high-temperature environments. - Chemical Resistance
-Resists a wide range of aggressive chemicals, including:
– Fuels
– Oils
– Acids
– Solvents
– Maintains integrity in harsh conditions - Durability & Longevity
– Long term durability with resistance to
– Oxidation
– UV light
– Ozone - Low Permeability
- Strength & Flexibility
– Maintains elasticity and performance under extreme pressure and temperature - Versatile Applications–
– Available in various grades including low-temperature formulations, making it suitable for everything from aerospace to food processing.
Popular Viton™ Fluid Sealing Products?
A wide range of Viton™ fluid sealing products is available, valued for their outstanding resistance to chemicals, fuels, and high temperatures.
Common products include Viton™ O-Rings, used extensively in the automotive, aerospace, and chemical processing industries, and oil seals, ideal for pumps, engines, and rotating equipment. Gaskets, sheeting, and cord are also available for custom sealing applications across sectors such as pharmaceuticals, food and beverage, and power generation.
For more specific requirements, moulded components, diaphragms, and washers are used in valves, regulators, and compact mechanical assemblies. These products offer long-lasting performance in some of the most demanding industrial environments.
A Guide To Viton™ – FAQ
“What is Viton™ made of?”
Viton™ is a synthetic rubber, known as a fluoroelastomer, made from fluorocarbon-based polymers.
“Is Viton™ the same as rubber?”
It is a type of synthetic rubber. However, it is far more resistant to heat, chemicals and degeneration. It performs better in these areas compared to standard elastomers such as Nitrile or Silicone.
“Why is Viton™ different?”
Viton™ is the most popular choice in applications and industries that require chemical exposure, ability to withstand extreme temperatures and long-term endurability. Unlike traditional rubber materials, like Nitrile or EPDM, Viton™ maintains its flexibility and durability in extreme environments.
“Is Viton™ Food safe?”
Some specialised grades of Viton™ are safe for use in the food and beverage industry and meets FDA, EC1935/2004 & EC2023/2006 European Regulation standards.
“Can Viton™ be used outdoors?”
Yes. It’s excellent resistance to environmental factors and durability makes it ideal for outdoor use.
“Is Viton™ worth it in terms of cost?”
Viton™ is typically more expensive than other types of rubbers and elastomers, but it’s benefits such as durability, longevity and low-maintenance requirements make it a more cost-effective option in the long run.
