What is the difference between FFKM, FKM (Viton®), and HNBR?

The main difference lies in their specific properties. FFKM offers the highest chemical resistance (universal), thermal stability up to 300°C, and high purity, ideal for semiconductors, aerospace, and critical applications. FKM (Viton®) offers excellent high-temperature resistance (230°C) and chemical resistance, but lower universal chemical resistance than FFKM, ideal for automotive and aerospace. HNBR offers good oil resistance and temperature (160°C), but lower chemical and thermal resistance than FFKM, ideal for automotive and industrial applications.

What temperature does FFKM withstand?

FFKM has exceptional thermal stability: maximum continuous operating temperature of 300°C, minimum operating temperature of -20°C, and maximum intermittent temperature of 315°C. It maintains its mechanical and chemical properties in extreme thermal conditions where other elastomers degrade quickly.

What presentations are available for FFKM?

FFKM is available in multiple presentations: O-rings in a wide range of sizes, custom gaskets and seals, gaskets to specifications, profiles and cords for specific applications, molded parts for complex geometries, and sheets and plates for custom cutting. Contact us for a personalized quote.

Does FFKM have certifications or quality standards?

Yes. Everest Group's FFKM meets the highest quality standards for critical applications: high purity ideal for semiconductors and pharmaceuticals, low particle generation essential for clean rooms, plasma resistance perfect for manufacturing processes, ASTM certifications, and pharmaceutical grade available for medical applications. These characteristics ensure our FFKM meets the most demanding reliability and safety requirements.
