Seal Degradation in Wet Processing? Here’s How Kalrez® Solves the Challenge.
DuPont™ KalrezⓇ perfluoroelastomer parts have been used successfully in highly aggressive sealing environments for over 40 years. Kalrez parts have excellent chemical and thermal stability and have been specially formulated and processed to meet the unique requirements of wafer processing environments. DuPont offers molded O-Rings and custom seals using a series of specialty products and ultrapure processing for the semiconductor industry. Ultrapure processing is standard for all semiconductor product grades.
Product Selector for Wet Processes
The following table provides a quick and easy tool for the selection of Kalrez parts depending on the production process type:
Typical Applications for Wet Processes:
Door/lid seals Drain seals Seals for chemical
Containers Fittings Seals for filters/connectors
Flow meters Flow controllers Valves
Current KalrezⓇ Product Offering for Wet Application: KalrezⓇ W240UP
KalrezⓇ W240UP perfluoroelastomer parts are a black product for high volume O-rings and custom parts for filters, valves, pumps and other wet manufacturing processes requiring a wide range of chemical resistance. Kalrez W240UP provides an excellent combination of properties (resistance to acids/bases) and is the product of choice for wet processes as an upgrade from standard elastomers, i.e. FKM, EPDM, etc. Thanks to Ultrapure clean process, Kalrez W240UP perfluoroelastomer parts exhibit very low particle generation.
Chemical Resistance:
Kalrez® W240UP demonstrates broad resistance to commonly used wet process chemicals, including aggressive acids, bases and cleaning agents. This chemical stability ensures reliable sealing performance even under continuous exposure, helping fabs maintain tight process control and high wafer yields.
