Abstract
The principal objective of incorporating pigments in the polymer is to introduce color either for aesthetic reasons or for the functional requirements. The enhancement of extrusion process parameters is necessary for the proper dispersion of pigment in the polymer. In the study presented three influential processing parameters during extrusion of polymer compound are speed, temperature and feed rate. The experimental design software with Box Behnken (BBD) methodology is being utilized for the optimization. The optimized model and experimental data exceeds the analytical examination making the formulation of model crucial. Also, it was found that the extrusion parameters have strong impact on color characteristics DL, Da and Db which is determined through the analysis of variance (ANOVA). Moreover, specific mechanical energy was calculated for the experimental runs and it was revealed that the specific energy decreases with increase in feed rate.
