The invention relates to a process for producing a fluoropolymer composition with improved chemical, thermal and color stabilities, and a reduced level of residual surfactants (both fluorosurfactants and non-fluorosurfactants. Such improvements, as indicated by total oxidizable carbon (TOC) and pellet yellowness index (YI), can be accomplished in a cost-effect manner through the use of a dewatering extruder. The dewatering extruder combines several typical unit operations into a single operation, producing solid fluoropolymer having significantly reduced total oxidizable carbons, a lower yellowness index and minimal amounts of surfactants.
