As an expert in the field of polymer materials, I can provide you with a detailed explanation regarding FKM and Viton.

FKM, which stands for Fluoroelastomer, is a category of synthetic rubber that is known for its exceptional resistance to heat, chemicals, and weathering. It is a polymer that contains carbon-fluorine bonds, which contribute to its unique properties. FKM is widely used in various industries due to its ability to maintain its elasticity and performance over a broad range of temperatures, typically from -20°C to +200°C, and in environments where exposure to aggressive chemicals is common.

Viton, on the other hand, is a registered trademark of DuPont Performance Elastomers. It is a brand name for a specific type of FKM, which has been developed and marketed by DuPont. Viton is known for its high performance and quality, and it is used in applications that require the utmost in resistance to heat, chemicals, and other harsh conditions.

While FKM is a general term that encompasses a category of fluoroelastomers, Viton is a specific brand within that category. It is important to note that not all FKM materials are Viton, but Viton is indeed an FKM. There are other manufacturers that produce FKM materials, and they may have their own proprietary names for their products. For example, Zrunek uses the designation FPM for all of its fluoro-elastomer materials, which is another term that is often used interchangeably with FKM.

The choice between different FKM materials, including Viton, depends on the specific requirements of the application. Factors such as temperature range, chemical exposure, and the desired physical properties of the rubber will guide the selection process. It is also crucial to consider the compatibility of the FKM with other materials in the system and the long-term performance under the intended operating conditions.

In summary, FKM is a broad term for a category of high-performance rubber materials, and Viton is a well-known brand within that category, offering specific formulations that are tailored to meet the demands of various industries. When selecting an FKM material, it is essential to consider the brand, the specific formulation, and how it aligns with the needs of the application.
