DuPont Dow Elastomers will highlight Kalrez perfluoroelastomer parts.

Said to offer seal durability and cleanliness in environments where other seal materials fail, Kalrez 6221 and 6230 perfluoroelastomer parts are intended for pharmaceutical and food processing, and offer FDA-compliant standard and custom seals, and sanitary gaskets. Meanwhile Kalrez Spectrum 7075 sets a new industry standard for severe CPI sealing applications. It offers enhanced sealing force retention and higher thermal resistance up to 327ºC, broader chemical resistance and better cool down set recovery.

Kalrez Spectrum 6375 is said to provide good performance with a wide range of chemicals. Its patented curing system permits continuous upper service temperatures of 275ºC in mechanical seals, valves, flanges and pumps.
