When it comes to choosing the right material for sealing applications, Viton and FKM are two popular options. Both materials offer a number of benefits, but there are also key differences that may make one more suitable than the other for specific applications. In this article, we will compare Viton and FKM to help you determine which is better suited for your needs.
Chemical Resistance.
Viton and FKM are both known for their excellent chemical resistance, making them ideal for use in a wide range of applications. However, there are some differences between the two materials when it comes to their compatibility with certain chemicals. Viton is more resistant to chemicals such as acids and fuels, while FKM may be better suited for applications involving oils and lubricants.
Temperature Resistance.
Another important factor to consider when choosing between Viton and FKM is temperature resistance. Viton has a higher temperature resistance compared to FKM, making it a better choice for high temperature applications. FKM, on the other hand, may be more suitable for applications where extreme temperatures are not a concern.
Compression Set.
Compression set refers to the ability of a material to return to its original shape after being compressed. Viton generally has a lower compression set compared to FKM, meaning it is less likely to deform over time. This makes Viton a better choice for applications where durability and long-term performance are important.
Cost.
Cost is also an important factor to consider when choosing between Viton and FKM. Viton is typically more expensive than FKM, which may be a consideration for applications where cost is a primary concern. However, the higher cost of Viton is often justified by its superior performance and longevity.
Conclusion.
In conclusion, both Viton and FKM are excellent materials for sealing applications, each with its own set of advantages and disadvantages. Viton is known for its high temperature resistance, excellent chemical resistance, and low compression set, making it a popular choice for a wide range of applications. FKM, on the other hand, may be more cost-effective and is better suited for applications involving oils and lubricants.
Ultimately, the choice between Viton and FKM will depend on your specific application requirements, budget, and performance expectations. If you need help determining which material is best suited for your needs, feel free to contact us for expert advice and guidance.
