Bestfluor\u00ae 3575 is a black, low compression set perfluoroelastomer (FFKM) designed for dry and wet semiconductor process environments. It features excellent chemical resistance, good mechanical properties and outstanding thermal stability, with low weight loss in reactive plasmas and good resistance to thermal cycling. Not recommended for amine environments. Ultrapure post-cleaning and clean packaging are available as options.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
