Composition Suitable for Thin-Wall Injection Molded Articles |
摘要 |
Compositions suitable for manufacturing injection molded articles having a minimum wall thickness of from 500 μm to 2.0 mm comprise from: (A) 2 to 15% by weight of a propylene-ethylene copolymer having substantially isotactic propylene sequences; (B) 85 to 98% by weight of a random polypropylene copolymer having from 2.5 to 5.0% by weight units derived from ethylene and a melt flow rate of from 25 to 130 grams/10 minutes (g/10 min); and (C) 500 to 2500 ppm by weight of a nucleator/clarifier additive (based on the weight of the random polypropylene copolymer). Typically, the melt flow rate of the compositions is from 20 to 125 g/10 min, and the propylene-ethylene copolymer comprises at least 75% by weight propylene and has a melt flow rate from 4 to 30 g/10 min.
