Kalrez® W240UP Parts Product Overview:

Perfluoroelastomer components made by DuPont™ Kalrez® W240UP are intended for use in semiconductor wet processes, including wafer cleaning tools, wet etch tools, catalyst development tools, and filters, pumps, and valves. In demanding wet applications, Kalrez® W240UP can fulfill market demands and improve process dependability.

The DuPont tradition of producing high-value perfluoroelastomer parts to prolong equipment Mean Time Between Repair (MTBR) is carried on by Kalrez® W240UP, which offers an exceptional combination of qualities such as:

1.Resistance to acids and bases at maximum service temperatures up to 230°C (446 °F). 

2.Low metal extractables

Compared to other common perfluoroelastomer components used in semiconductor wet processes, it performs efficiently. Performance comparison between DuPont™ Kalrez® W240UP and DuPont™ Kalrez® 6375UP perfluoroelastomer parts :

Physical and thermal characteristics: The physical characteristics of Kalrez® W240UP and Kalrez® 6375UP parts are similar. In applications where operating temperatures reach 230 °C, Kalrez® W240UP components may be a good substitute for Kalrez® 6375UP parts.

Chemical resistance: Our lab’s chemical immersion tests revealed no appreciable differences between Kalrez® W240UP and Kalrez® 6375UP parts in terms of chemical resistance. 

Metal Extractables: When compared to the standard FFKM utilized in the industry, Kalrez® W240UP exhibits very low metal extractables and comparable metal extractable performance to Kalrez® 6375UP.
