DuPont™ Kalrez® chemical processing seals are a proven sealing option for high-temperature (327°C), aggressive-chemical processing applications.
DuPont offers engineering thermoplastic materials that are durable, cost-effective, and meet a variety of regulatory requirements for food contact equipment and storage.
Kalrez® perfluoroelastomer parts include a range of high pressure, high temperature (HPHT) seals for oil and gas industry downhole uses, with resistance to rapid gas decompression, heat and chemicals.
Kalrez® parts used for aircraft engine seals are designed with properties to work in extreme temperatures and withstand aggressive aerospace fluids, including jet fuels and lubricating oils.
Kalrez® semiconductor processing seals are a field-proven choice for wafer-fabricating operations, including deposition, etch, ash/strip, thermal and wet-chemical processes.
In photovoltaic manufacturing, Kalrez® parts are a cost-effective upgrade over standard elastomers for bulk crystalline silicon and thin-film photovoltaic processes.
DuPont oil and gas polymers are chosen for tested and demonstrated barrier, adhesion, thermal and chemical resistance in exploration, production and refining sealing uses.
