Kalrez® 4079

Kalrez® 4079 is a black, low compression set compound for use in many dry and wet semiconductor process environments. It has excellent chemical resistance, good mechanical properties and outstanding thermal stability. Kalrez® 4079 exhibits low weight loss in reactive plasmas and has good response to temperature cycling effects. It is not recommended for use in amines. A maximum continuous service temperature of 316°C is suggested. Short excursions to higher temperatures are also possible. Ultrapure post-cleaning and packaging is optional.

For many applications, low volume swell of elastomers is critical for proper equipment operation. Excessive swell may cause permanent seal failure due to equipment hang-up, extrusion, etc. While other physical property testing may be needed to adequately define product performance in a particular application, volume swell is an excellent indicator of resistance to chemical attack. A summary of the internal and external compatibility tests performed to determine the volume swell of 

Kalrez® 4079UP in various semiconductor wet process environments is provided.
