  • Patent number: 8497333
    Abstract: Disclosed is a polylactic acid composition with improved heat-resistance and improved impact-resistance. Specifically, in the disclosed polylactic acid composition, both impact strength and heat-resistance are improved by mixing 30 to 80 wt % of polyketone and 10 to 40 wt % of modified rubber. The disclosed polylactic acid composition does not only exhibit excellent in heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance, etc., but also has improved impact-resistance and improved heat resistance. Thus, it is possible to employ polylactic acid as a bioplastic in interior/exterior parts of a vehicle.

  • Patent number: 8378023
    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.
