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%.

Abstract: The present disclosure generally relates to carbon fiber reinforced polyolefin compositions, which may have a relatively low density. The compositions may include a thermoplastic olefin, a filler component, a compatibilizer, and/or an additive package. In some embodiments, the filler component includes a plurality of carbon fibers. In addition, articles of manufacture and methods of making a carbon fiber reinforced polyolefin composition are provided.
