FKM fluoroelastomer rubber compounding
Preferred creates a wide variety of custom rubber compounds from high-performance fluoroelastomer (FKM and FEPM) and perfluoroelastomers (FFKM).
Also known as fluoro rubber, fluoroelastomer and perfluoroelastomer offer extreme high temperature performance and resist a variety of acids and fluids along with ozone and weather. They have very good compression set and fuel resistance.
FKM, FFKM and FEPM rubber properties
FKM and FFKM have poor resistance to phosphate esters and ketones and poor low temperature capabilities. Successfully compounding FKM requires excellent control of the manufacturing process. Preferred produces FKM, FFKM and FEPM compounds in sheets, slab, strip and calendared and can help you engineer the right mix for your aapplication.
Fluoroelastomer and perfluoroelastomer compound uses
Uses for fluoroelastomer and perfluoroelastomer compounds include high temperature and acid resistant seals, oil resistant gaskets, offshore seals, fuel-resistant cable jackets and temperature-resistant seals, gaskets, O-rings, tubes and more.
Transportation applications include seals, gaskets, and hoses used in fuel systems, air intake systems, turbocharger systems, and engines or transmissions. Industrial uses include seals and other components used in chemical processing equipment, utility expansion joints, and roller covers.
Fluoro rubber trade names
Polymer manufacturers offer a variety of grades of FKM and FFKM to meet specific end-use and processing needs. These differences are often in specific chemical resistance and mechanical properties. Preferred can help you determine which brand and grade is best for your application.
Trade names for fluoroelastomers include Viton® and Kalrez® from DuPont Performance Elastomers; Dyneon™ from 3M Company; Dupra™ and Dai-El from Daiken Industries, Inc.; Levatherm™ from Lanxess; Technoflon™ from Solvay Plastics and Dowhon FKM from RHD Polymers & Chemicals.
