Perfluoroelastomer Technical Datasheets

FF601 - 60 durometer, black, perfluoroelastomer optimized for high chemical and moderate thermal stability

FF602 - 60 durometer, white, perfluoroelastomer optimized for high chemical and moderate thermal stability

Both materials exhibit:

low permeability and resistance to swell in a broad range of chemicals
low extractables in a wide range of chemicals
good chemical resistance even at elevated temperatures (Note: inner core material will need to be considered under maximum temperature conditions)
an excellent ability to be molded to highly complex shapes
