POLYPROPYLENE COMPOSITION

摘要

PURPOSE: A polypropylene resin composition is provided to ensure excellent mechanical properties such as shock resistance, rigidity and heat resistance, and excellent appearance by suppress the generation of flow marks. CONSTITUTION: A polypropylene resin composition includes: crystalline olefin-based resins that are single or a mixture of materials, selected from the group consisting of isotactic polypropylene and alpha-olefin-propylene copolymers; polyolefin-based elastomers; and talc. A melt index ratio of the crystalline olefin-based resins to the polyolefin-based elastomers is 10:1 - 100:1.
