FFKM for Extreme Temperatures
Applications that experience both extreme low and extreme high temperatures require sealing materials capable of maintaining flexibility, chemical resistance, and mechanical integrity across a wide operating range. FFKM (perfluoroelastomer) O-rings, gaskets, custom parts, and tubes designed for extreme temperature environments are engineered to perform from approximately -20°C to 300°C (-4°F to 572°F) or beyond, depending on the compound and application conditions.
At Canyon Components, Canrez® FFKM compounds such as CP80WH01, CP75BK40, CP80BK11, and CP65TB11 are specifically developed to handle these wide temperature swings without sacrificing sealing performance. These materials are ideal for applications where systems cycle between cold startup conditions and high temperature operation, or where both extremes may occur intermittently. Compared to Kalrez® and Chemraz®, Canrez® FFKM offers a strong balance of performance, availability, and cost efficiency, making it an excellent solution for demanding, multi-temperature environments.
Unlike standard elastomers that may harden in the cold or degrade in heat, Canrez® FFKM O-rings, gaskets, and custom parts maintain elasticity, low compression set, and chemical resistance across a broad temperature spectrum. Canyon Components engineers work closely with customers to ensure proper compound selection, seal design, and material optimization for long-term reliability in extreme temperature applications.
Common names include: FFKM, Perfluoroelastomer, Perfluorinated Rubber. Trade names: Canrez®, Kalrez®, Chemraz®, Simriz®, Parofluor®.
