  • Publication number: 20120271001
    Abstract: The present invention provides a polyketone composition having about 40˜90 wt % of polyketone, about 5˜40 wt % of polyamide, and about 5˜20 wt % of modified rubber. The composition of the present invention greatly improves the impact resistance of polyketone, which has increased heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance or the like, and thus may be widely applied in various industrial fields, such as automotive parts including wheel covers, wheel caps, fuel filler necks, fuel tanks, fuel tubes, center fascias, door handles, roof rack covers, gear, junction boxes, connectors, seat backs or the like, electric/electronic parts, and household items, thereby providing durability of the parts and price competition.

  • Publication number: 20120010340
    Abstract: The present invention provides a polypropylene resin composition prepared by adding a black coloring agent and metal oxide nanoparticles to polypropylene or a mixture of polypropylene and rubber to have a black high gloss finish. The polypropylene resin composition prepared according to the present invention can be used as a substitute for expensive engineering plastics, which have been used for vehicle interior and exterior components with a black high gloss finish, and thus can contribute to a reduction in manufacturing cost and weight and environmentally friendly characteristics.

  • Publication number: 20110130506
    Abstract: Disclosed is a thermoplastic polyolefin (TPO) nanocomposite composition, more particularly a TPO nanocomposite composition including a polypropylene resin, a polyethylene resin, a rubber resin, a nanoclay master batch and a glass bubble master batch. Since the disclosed TPO nanocomposite composition has low specific gravity and superior gloss reducing effect and scratch resistance, it may be usefully applied to light automobile parts, uncoated automobile exterior parts, or the like.
