  • Patent number: 11904515
    Abstract: Molded-in-color thermoplastic polyolefin (TPO) compositions useful for making automotive components, such as injection molded parts, as well as other articles of manufacture are described. The molded-in-color composition has a ?E* value?2.0 (compared to a painted color master), a gloss measured at 60° from about 76 to about 90 GU, a density ranging from about 0.9 to about 0.97 g/cm3, a melt mass flow rate from about 15 to about 40 g/10 min (ASTM D 1238, 230° C./2.16 kg), a flexural modulus between about 600 to about 2000 MPa, and an as-molded shrinkage between about 0.6% and about 1.4%. The compositions can be used to prepare molded-in-color components that can undergo additional clear coating steps as required by the automotive application. The clear coated molded-in-color components have a gloss measured at 20° from about 85 to about 95 GU and a gloss retention after mar between about 85% and about 93%.

  • Patent number: 10358547
    Abstract: The present disclosure generally relates to low density compositions useful for making automotive components, such as molded parts, as well as other articles of manufacture; such compositions comprise (a) a polyolefin comprising polypropylene, a propylene-ethylene block copolymer, or combinations thereof, wherein the polyolefin blend is present in an amount ranging from about 53 wt. % to about 65 wt. %, based on a total weight of the composition; (b) a first elastomer, a second elastomer, and an impact-modifying compatibilizer, wherein the combined weight percent of components (b) ranges from about 27 wt. % to about 32 wt. %, based on the total weight of the composition; (c) a filler present in an amount ranging from about 5 wt. % to about 12 wt. %, based on the total weight of the composition; and (d) an additive package present in an amount ranging from about 0.5 wt. % to about 5 wt. %.
