摘要:
Blended compositions that can include one or more thermoplastic polymers and one or more organic fillers and methods for making and using same. The blended composition can have a Notched Izod Impact Strength of at least 20 J/m to about 600 J/m, measured according to ASTM D256-10, and a melt index of about 1 g/10 min to about 100 g/10 min, measured according to ASTM D1238-13, procedure B. The thermoplastic copolymer can include a blend of a polypropylene homopolymer and a copolymer of propylene and a comonomer. The comonomer can include ethylene, a C4 to C20 olefin, or any mixture thereof. The copolymer of propylene and the comonomer can include about 0.5 wt % to about 40 wt % of the comonomer. The blended composition can include about 5 wt % to about 30 wt % of the organic filler based on the combined weight of the thermoplastic copolymer and the organic filler.
