Are FKM and Viton the Same?

When it comes to seal materials and components, it's essential to understand the differences between various options available in the market. Two common terms that are often used interchangeably are FKM and Viton. While they may seem similar, there are some key distinctions between these two materials that are important to note.

What is FKM?

FKM stands for fluorocarbon rubber, which is a type of synthetic rubber that is known for its excellent resistance to heat, chemicals, and oil. FKM is widely used in industries where seals and gaskets are required to withstand harsh conditions and extreme temperatures. It is also known for its durability and reliability, making it a popular choice for seals and gaskets in a wide range of applications.

What is Viton?

Viton is a specific brand of FKM that is manufactured by the company Chemours (formerly a part of DuPont). While Viton is technically a type of FKM, it has become so popular that many people use the term "Viton" to refer to all fluorocarbon rubber materials. Viton is known for its high performance and is often used in industries such as automotive, aerospace, and chemical processing.

Differences between FKM and Viton.

While FKM and Viton are closely related, there are some key differences between the two. One of the main distinctions is that Viton is a trademarked brand name owned by Chemours, while FKM is a more generic term used to describe fluorocarbon rubber in general. This means that all Viton materials are FKM, but not all FKM materials are Viton.

Another difference between FKM and Viton lies in their composition. Viton is known for its high fluorine content, which gives it superior resistance to chemicals, heat, and oil. On the other hand, FKM materials can vary in their composition, with some types offering different levels of performance and durability.

Choosing Between FKM and Viton.

When selecting a material for seals and gaskets, it's important to consider the specific requirements of your application. If you need a material that offers superior resistance to harsh chemicals, high temperatures, and oil, Viton may be the best choice for you. However, if you're looking for a more cost-effective option that still offers good performance, other types of FKM materials may be suitable for your needs.

Ultimately, the best choice between FKM and Viton will depend on your specific application and performance requirements. Consulting with a professional who specializes in seal materials can help you determine the most suitable option for your needs.

Conclusion.

In conclusion, while FKM and Viton are closely related materials, there are some key differences between the two that are important to understand. Viton is a brand name of FKM that offers high performance and excellent resistance to chemicals, heat, and oil. On the other hand, FKM is a more generic term that encompasses a range of fluorocarbon rubber materials with varying compositions and properties. When selecting a material for your seals and gaskets, it's crucial to consider the specific requirements of your application to choose the best option for your needs.
