Fluorocarbon (FKM) vs. Viton®: What’s the Difference?
In the world of engineering and manufacturing, material selection plays a pivotal role in determining the performance and longevity of components. When it comes to sealing applications, two commonly used materials are Fluorocarbon and Viton®. In this guide, we’ll delve into the differences between these materials, their properties, and their applications.
Understanding Fluorocarbon and Viton®
Fluorocarbon, also known as FKM (fluoroelastomer), is a synthetic rubber material recognized for its exceptional chemical resistance and temperature tolerance. Derived from fluorinated hydrocarbons, it is highly resistant to oils, fuels, acids, and a wide range of chemicals. This makes it a preferred choice for demanding sealing applications in industries such as automotive, aerospace, and chemical processing.
Viton®, on the other hand, is a brand name for fluoroelastomer compounds developed by the Chemours Company. It is specifically formulated for enhanced performance in sealing applications, offering similar chemical resistance and temperature stability as Fluorocarbon but optimized for improved sealing effectiveness, especially in dynamic applications.
Technical Features Comparison
| Feature | Fluorocarbon (FKM) | Viton® |
|---|---|---|
| Chemical Resistance | Excellent resistance to oils, fuels, and chemicals | Superior resistance, especially in aggressive environments |
| Temperature Tolerance | Typically up to 200°C | Up to 250°C |
| Mechanical Properties | High tensile strength and tear resistance | Enhanced flexibility and resilience |
| Compression Set | Low compression set | Very low compression set |
| Applications | Automotive, aerospace, chemical processing | Critical sealing applications in high-temperature environments |
Differences Between FKM and Viton®
While both FKM and Viton® are types of fluoroelastomers, there are key differences that set them apart:
| Aspect | FKM | Viton® |
|---|---|---|
| Brand Recognition | General term for fluoroelastomers | Specific brand by Chemours |
| Formulation | Various manufacturers and formulations | Specific formulations by Chemours |
| Performance | Good for general applications | Optimized for high-performance sealing |
| Cost | Generally lower cost | Higher cost due to brand reputation |
Applications of FKM and Viton®
Both FKM and Viton® are widely used in various industries due to their excellent properties. FKM is commonly found in automotive seals, gaskets, and O-rings, while Viton® is often preferred for critical applications in the aerospace and chemical processing industries.
For instance, Viton® is ideal for environments where exposure to aggressive chemicals and high temperatures is prevalent. In contrast, FKM is suitable for a broader range of applications, including those that do not require the extreme performance characteristics of Viton®.
Summary of Key Insights
Fluorocarbon and Viton® are both highly versatile materials known for their exceptional chemical resistance and temperature stability, making them ideal for sealing applications in demanding industrial environments. While Fluorocarbon encompasses a broad range of fluoroelastomer materials, Viton® stands out as a specialized formulation optimized for enhanced sealing performance.
Understanding the differences between these materials is crucial for selecting the most suitable option for specific application requirements, ensuring optimal performance and reliability.
