  • Publication number: 20150315365
    Abstract: Provided are a fiber-reinforced polypropylene resin composition, and a molded article prepared therefrom having good grain transfer characteristics, a good appearance, a soft surface texture, high rigidity, and high heat resistance. The fiber-reinforced polypropylene resin composition contains a specific propylene-ethylene random copolymer and a specific fiber, and optionally contains a propylene-ethylene block copolymer satisfying four conditions, such as sequential polymerization in the presence of a metallocene catalyst, a thermoplastic elastomer satisfying two conditions, such as MFR, and a specific propylene polymer resin.

  • Publication number: 20140242335
    Abstract: The present invention is to provide a fiber reinforced polypropylene resin composition which has low shrinkage, excellent grain transferability, flaw resistance and moulded appearance, can provide a moulded article having a smooth and soft tactile sensation on the surface thereof without foaming and has high rigidity, high impact strength and high heat resistance, as well as a method for producing the same and a moulded article thereof. These are implemented by a fiber reinforced polypropylene resin composition containing a propylene-ethylene block copolymer which satisfies four requirements such as sequential polymerization with a metallocene catalyst, a specific fiber and optionally a specific modified polyolefin, a thermoplastic elastomer which satisfies two requirements such as MFR, a specific propylene polymer resin and a specific fatty acid amide.
