Composition of polyketone with high impact strength
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.
