Abstract
A composition includes a first amorphous fluoropolymer having a first Mooney viscosity ML 1+10 @ 121° C. less than 60 and a second amorphous fluoropolymer having a second Mooney viscosity ML 1+10 @ 121° C. greater than 80. The composition further includes at least one of a non-fluorinated, thermoplastic polymer as a major component of the composition or a polymer processing additive synergist. A method of reducing melt defects during the extrusion of a polymer is also provided. Use of a combination of the first and second amorphous fluoropolymers as a polymer processing additive is also provided.
