US 2025/0092219 A1 · POLYPROPYLENE COMPOSITION RESISTANT TO THERMO-OXIDATIVE AGING, PREPARATION METHOD AND USE THEREOF

Abstract

The present disclosure relates to a polypropylene composition resistant to thermo-oxidative aging, a preparation method and a use thereof. The polypropylene composition resistant to thermo-oxidative aging comprises polypropylene, a toughener, a filler, carbon black and other additive or additives. The polypropylene composition resistant to thermo-oxidative aging provided in the present disclosure has a better thermo-oxidative aging resistance by adding specific carbon black, without any complicated surface modification for the carbon black, and the polypropylene composition can be widely used in auto parts or cables.
