New DuPont perfluoroelastomer material provides longer seal life

DuPont has launched a new perfluoroelastomer part for use in demanding high volume industrial markets for applications such as sensors, sprayers, injectors, diving seals, and microvalves.

The Kalrez CP222 can enable manufacturers to reduce total operating sealing costs due to its longer seal life and high chemical and temperature resistance.

The material is well-positioned for O-rings and custom parts with an outer diameter up to 2” (50.8 mm).

Other sizes and shapes can be addressed through developmental projects in cooperation with the customer.

DuPont has also developed Kalrez LS222 to complement Kalrez CP222 for customers serving multiple markets such as the life science industry.

Kalrez LS222 is an FDA- and USP VI-compliant high volume seal and is manufactured to meet the high standards of safety, hygiene, and quality control of the food and pharmaceutical industries.

DuPont Kalrez parts last longer and seal more effectively than other elastomers in demanding processing environments.

They resist over 1,800 different chemicals, while offering the high temperature stability of PTFE (327°C).

The long-term, proven performance of Kalrez parts can mean less frequent seal changes, repairs, and inspections, increasing process and equipment uptime for greater productivity and yield.

They are used across a wide array of sectors including life sciences, industrial, food and beverage, and pharmaceuticals.
