Gallagher Fluid Seals is a long-time partner of DuPont™, predominantly focusing on the Kalrez® line of products which is part of DPM. The latest perfluoroelastomer offering from DPM, Kalrez® Spectrum™ 7275, offers a higher level of sealing performance in the most aggressive chemical processing and manufacturing environments.
"Kalrez® Spectrum™ 7275 is an innovative product tailored specifically for the most demanding and aggressive environments in the chemical processing industry. Our latest grade of Kalrez® offers many benefits including an increased MTBR (mean time between repair) which contributes to reduced maintenance costs and longer equipment life for our customers,” DuPont's Shane Campbell said in a news release. “DuPont is always looking for opportunities to innovate in ways that help our end-users and customers, and we’re pleased to be able to offer a sealing material which helps to improve process safety and MTBR.”
Kalrez Spectrum 7275 is a perfluoroelastomer that provides long life sealing in an array of aggressive chemical environments that typically make sealing difficult: ethylene oxide, acrylic monomers, silanes and chlorosilanes, and strong oxidizers such as nitric acid, chlorine and chlorine dioxide.
It has demonstrated improved chemical and compression set resistance and mechanical property retention when compared to competitor's elastomers.
Kalrez Spectrum 7275 is based on a proprietary cross-linking system, and is uniquely identified by its light brown shade.
Targeted applications include industries that depend on mechanical seals, pumps, valves, compressors, filtration columns and analytical equipment for their critical processes.
It is the latest addition to a portfolio of high-performance materials DuPont offers to the chemical processing world, backed by a world-class technical support team with broad expertise in sealing solutions. Kalrez Spectrum 7275 comes in a range of standard O-ring sizes and custom parts for a wide range of sealing applications.
