DuPont is launching Kalrez® OG193 perfluoroelastomers, a 95 durometer, FFKM compound that exhibits an excellent balance of properties for oil and gas applications. Kalrez® OG193 combines best-in-class Rapid Gas Decompression (RGD) performance and chemical resistance with good low temperature and thermal stability. It passes the acceptance criteria for multiphase sour ageing according to ISO23936-2 and scores the highest rating at the Rapid Gas decompression test. It is an ideal fit for various applications in both upstream and downstream, such as oilfield production/completion equipment, wireline and drilling tools, pumps, mechanical seals, valves, compressors, and more.
With oil production being pushed into more extreme conditions and harsher environments, there is limited margin for error, considering the high costs associated to unplanned downtime. Manufacturers, contractors, and well operators need to operate with equipment purposefully developed to resist harsh environments and offer a margin for safety. Choices must be made around selecting perfluoroelastomers based on their high chemical resistance vs. low-temperature performance. Kalrez® OG193 Perfluoroelastomer offers versatility without compromise for a variety of key parts including O-rings, packers, bonded seals, chevron stacks, T-Seals, and many other applications including production and completion equipment, pumps, valves, compressors, and mechanical seals.
