Abstract: A polymer processing additive (PPA) composition to improve melt extrusion of an extruded composition comprising an extruded thermoplastic polymer, the PPA composition comprising of at least one fluoropolymer having a Mooney viscosity (ML 1+10 @ 121° C.) of about 30 to about 90 (ASTM D 1646-06 Part A with an MV 2000 instrument (available from Alpha Technologies, Ohio) using a large rotor (ML 1+10) at 121° C.) and at least one polydiorganosiloxane polymer, wherein said extruded thermoplastic polymer is selected from a polypropylene homopolymer, a polypropylene copolymer, and a combination thereof. Also provided is a method for extruding polymers using the PPA compositions, as well as extruded products comprising the PPA composition.
