Document Type and Number:
WIPO Patent Application WO/2024/029197
Kind Code:
A1
Abstract:
The present invention provides a polypropylene resin composition which contains a polypropylene polymer (component (A)) and a flame retardant (component (B)), wherein the polypropylene polymer (component (A)) satisfies the condition (a-1) and the condition (a-2) described below. Condition (a-1): Relative to the total amount of the polypropylene polymer (component (A)), the proportion of the component that has a molecular weight (M) of 2,000,000 or more as determined on the basis of the molecular weight distribution curve obtained by GPC measurement is 0.6% by mass or more. Condition (a-2): Relative to the total amount of the polypropylene polymer (component (A)), the proportion of the component that has a molecular weight (M) of 50,000 or less as determined on the basis of the molecular weight distribution curve obtained by GPC measurement is 16% by mass or more.
