  • POLYPROPYLENE - POLYETHYLENE BLENDS WITH IMPROVED PROPERTIES
    Publication number: 20220356330
    Abstract: Disclosed is a polymer composition comprising at least the following components A) 20 to 75 wt.-% based on the overall weight of the polymer composition of a polymer blend, comprising a1) polypropylene; a2) polyethylene; wherein the weight ratio of a1) to a2) is from 3:7 to 12:1; and wherein the polymer blend A) is a recycled material; B) 25 to 80 wt.-% based on the overall weight of the polymer composition of a virgin polypropylene homopolymer. Also disclosed are a process for manufacturing the polymer composition, a process for improving mechanical properties of a polymer blend A) by incorporating B) into A) and articles made from the resulting polymer composition.
    Type: Application
