Abstract
High purity perfluoroelastomer composites and processes for producing the same are provided. High purity composites may be formed from compositions comprising a crosslinkable fluoroelastomer terpolymer of TFE, PAVE, and CNVE, and functionalized PTFE, which may be crosslinked to form crosslinked composites having low metal content and low compression set. Emulsion mixtures for forming the high purity composites are also provided.
