Polypropylene resin composition with improved foaming capability

Abstract

Provided herein is a composition of a polypropylene resin with improved foaming capability with improved foaming capability, such as a polypropylene comprising a foaming agent master batch and a highly flowable polypropylene resin having non-controlled rheology. The resin composition exhibits excellent foaming quality and can be easily injected. The polypropylene resin with improved foaming capability comprises a mixture comprising from about 50% to about 80% by weight of a polypropylene resin having a mean molecular weight of about 45,000 g/mol to about 180,000 g/mol, from about 15% to about 30% by weight of a fiber reinforcing agent, and from about 2% to about 20% by weight of a foaming agent.
