Based on Orthogonal Experimental Analysis: Effects of Formulation Systems on the Mechanical, Heat Resistance, and Aesthetic Properties of High-Gloss Black PMMA/ASA Alloys

High gloss and heat resisting PMMA/ASA is applied in many fields such as automotive materials. There are many researches focusing on single properties but no comprehensive quantitative evaluation. In this work, we used orthogonal experiments and variance methods, along with a custom Python program, to conduct in-depth experimental analysis and provide a comprehensive evaluation of the performance of each component in the material system. The results demonstrate that this analysis method can appropriately assess the enhancements that each functional component contributes to corresponding performances. Additionally, it was observed that the strategy of blending high and low melt flow index PMMA affects the overall performance, as the application of high and low melt flow index PMMA changes the distribution and gradient of the functional components, significantly enhancing performance for certain surface or gradient-sensitive properties.
