Polymer compositions, articles made from such compositons, and methods for molding such compositions

摘要

A polymer composition comprises a thermoplastic polymer, a polymer additive selected from the group consisting of nucleating agents, clarifying agents, and combinations thereof, and a fluoropolymer. A molded article comprises at least one wall defining a cavity, the wall having an opening therein permitting access to the cavity. The wall comprises a polymer composition comprising a thermoplastic polymer, a polymer additive selected from the group consisting of nucleating agents, clarifying agents, and combinations thereof, and a fluoropolymer. A method for molding a polymer composition is also provided.

1. A polymer composition comprising:
(a) a thermoplastic polymer; (b) a polymer additive selected from the group consisting of nucleating agents, clarifying agents, and combinations thereof; and (c) a fluoropolymer, the fluoropolymer having a Melt Flow Index of about 4 to about 30 g/10 minutes as measured in accordance with ASTM D1238-04c at 265° C. using a 5 kg weight, wherein the polymer additive and the fluoropolymer are present in the polymer composition in a ratio of polymer additive to fluoropolymer of 8:1 to about 100:1 based on the total weight of the polymer additive and the fluoropolymer present in the polymer composition.
