Molding composition useful as e.g. wash liquor vessel and liquor pump casing comprises olefinic polymer containing glass fibers bonded to the olefin polymer by a compatibilizer, and phthalocyanine pigment as a nucleating agent

摘要

A molding composition comprises an olefinic polymer containing glass fibers (5 - 50 wt.%) bonded to the olefin polymer by a compatibilizer, and phthalocyanine pigment (10 -> 4> - 1 wt.%, preferably 10 -> 3> - 10 -> 1>) as a nucleating agent. An independent claim is included for preparation of the composition involving mixing the propylene polymer (initially melted) and the nucleating agent in a mixing apparatus at 180 - 320[deg]C; followed by mixing the glass fibers with the melt.
