Title:
POLYPROPYLENE THIN-WALL INJECTION MOLDING MATERIAL AND THIN-WALL INJECTION MOLDED ARTICLE MADE THEREFROM
Document Type and Number:
WIPO Patent Application WO/2023/000262
Kind Code:
A1
Abstract:
Provided in the present invention is a polypropylene thin-wall injection molding material, which comprises a polypropylene resin and a sorbitol compound, wherein the polypropylene resin is a homo-polypropylene, or a polypropylene containing less than or equal to 2 wt% of butene. By adding the sorbitol compound to the polypropylene resin, under high-temperature thin-wall injection molding, the haze of the polypropylene thin-wall injection molding material can be reduced while preserving less of the sorbitol compound, such that the thin-wall injection molded article has better mechanical properties, thermal properties, and optical properties. Further provided in the present invention is a polypropylene thin-wall injection molded article made from the polypropylene thin-wall injection molding material at a high temperature.
