Kalrez? 7075 as568-120FFKM-Dupont/kalrez杜邦美国进口全氟化橡胶O型圈密封件O型环USA
A new compound with enhanced physical performance properties including very low compression set （15% O- as568-120FFKM-Dupont/kalrez杜邦美国进口全氟化橡胶O型圈密封件O型环USArings per ASTM D 395B） and improved seal force retention. It is a carbon black filLED compound utilizing new and proprietary cure chemistry technology with mechanical properties designed for improving sealing performance in both high temperature environments and temperature cycling situations. 7075 joins the family of Kalrez ? Spectrum ? products designed for the chemical processing industry. 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. 7075 was specifically developed to be used as an O-ring or custom-sealing component in the chemical and hydrocarbon industries, with an improved thermal resistance that extends maximum service temperature to 327°C （620°F）. Kalrez ? Spectrum ? 7075 offers the enhanced elastomeric properties outlined above while providing a chemical resistance better than the industry standard set by Kalrez ? 4079.
Kalrez? 4079
A low compression set compound for general-purpose use in O-rings, diaphragms, seals, and other parts used in the process and aircraft industries. It is a carbon black-filled compound with excellent chemical resistance, good mechanical properties, and outstanding hot air aging properties. It exhibits low swell in organic an inorganic acids and aldehydes and has good response to temperature cycling effects. A maximum operating temperature of 316?C （600?F） is recommended, with short excursions to higher temperatures possible. This compound is not recommended for use in hot water/steam applications or in contact with certain hot aliphatic amines, ethylene oxide and propylene oxide.
