DuPont Mobility and Materials Kalrez® 7075 FFKM Perfluoroelastomer  (discontinued **)
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: Kalrez® Spectrum™ 7075 is designed specifically for the needs of the chemical processing industry. Compound 7075 broadens the family of Spectrum™ sealing options with a compound that has enhanced physical performance properties including very low compression set and improved seal force retention. To provide even greater sealing performance in dynamic applications where low friction is required, 7075 O-rings have a glossier finish than other Kalrez® parts. Kalrez® Spectrum™ 7075 is designed for general purpose use as an O-ring or custom-sealing component in the chemical and hydrocarbon processing industries. It is a carbon-black filled compound with mechanical properties designed for improving sealing performance in temperature cycling applications. 7075 has improved thermal resistance that extends maximum service temperature to 327°C. It is recommended that in each application the chemicals, service temperature and pressure be reviewed for the optimal compound selection.
