Core/Shell Polymer and Fluoropolymer Blending Blow Molding and Blown Film Process

A process is provided for extruding a partially crystalline melt-fabricable perfluoropolymers. The process comprises blow molding from a perfluoropolymer having polytetrafluoroethylene sub-micrometer particles dispersed therein. The perfluoropolymer composition is a core/shell polymer, with pelletiz...
