Plastics are prone to photo oxidative and thermal oxidative degradation under usage conditions due to their chemical nature. From sustainability and cost standpoint, there is an increasing focus on Mold-In-Color (MIC) plastic materials. Simultaneously customer’s expectations on the perceived quality of these MIC parts has been increasing with attractive color and glossy appearance. A study was conducted to analyze the product quality and durability aspects over a prolonged exposure to accelerated weathering condition. Material selected for this study were injection molded specimens of ABS and PC/ABS used in automotive passenger vehicles. Comparative analysis was conducted before and after weathering exposure at defined intervals by using the various tools like Fourier Transform infra-red spectrometer (FTIR), thermogravimetric analyzer (TGA) and universal testing machine (UTM), Izod impact tester, dynamic mechanical analyzer (DMA) to understand the impact on their chemical and mechanical properties. This study will be useful in understanding material behavior, durability, performance and product quality.
