INFRARED REFLECTIVE DARK COLORED POLYCARBONATE COMPOSITION |
| 摘要 |
Dark colored polycarbonate compositions and exterior automotive parts produced therefrom with infrared resistance additives are disclosed. The dark colored polycarbonate compositions and parts impart enhanced thermal management and reduce intrinsic heat up of darker materials by incorporation of an improved infrared resistance additive. The dark polycarbonate compositions and automotive parts may be used in various exterior applications including automotive glazing applications. |
