Abstract
Crosslinkable perfluoroelastomer compositions having low metal content and low compression set when crosslinked, and processes for producing the same, are provided. Compositions comprising terpolymers of TFE, PAVE, and CNVE having a metal content of less than 3000 ppb may be formed into high purity transparent perfluoroelastomer parts.
