Latest Patents

One of Yang's latest patents is for an automotive molded-in-color thermoplastic polyolefin with a clear coating for paint replacement and high gloss applications. This invention describes molded-in-color thermoplastic polyolefin (TPO) compositions that are useful for making automotive components, such as injection molded parts. The molded-in-color composition boasts a ΔE* value of ≤2.0 compared to a painted color master, a gloss measured at 60° ranging from about 76 to about 90 GU, and a density between about 0.9 to about 0.97 g/cm. Additionally, it features a melt mass flow rate from about 15 to about 40 g/10 min, a flexural modulus between about 600 to about 2000 MPa, and an as-molded shrinkage between about 0.6% and about 1.4%. These compositions can be utilized to prepare molded-in-color components that may undergo additional clear coating steps as required by automotive applications. The clear-coated molded-in-color components exhibit a gloss measured at 20° from about 85 to about 95 GU and a gloss retention after mar between about 85% and about 93%. Another notable patent involves carbon fiber reinforced polyolefin compositions and methods, which relate to low-density materials that include thermoplastic olefins, filler components, and carbon fibers.
