Fluoroelastomers (ASTM designation FKM, FFKM and FEPM) are used in sealing components such as o-rings, gaskets, shaft seals and flexible connectors where heat and/or aggressive chemicals will quickly degrade other types of rubber. In food processing high temperatures are used for cooking and preserving foods, which may be acidic, oily or fatty. In addition, rubber components are exposed to steam and caustic chemicals used to sanitize the equipment. In this environment fluoroelastomers will retain their sealing ability long after other elastomers have failed. Fluoroelastomer o-rings, gaskets and other seals therefore offer longer replacement cycles, less unplanned downtime and better protection against product contamination, which saves money and ensures a safer food processing environment.
