Study on effect of dispersion and processing parameters in microscopically evaluated colour of plastic grade

Abstract

The objective of this paper is to evaluate the influence of various processing parameters on the dispersion quality of polycarbonate compound. The influences of parameters, pigment size distribution, and morphology on the pigment dispersion were also studied. The information on pigment dispersion was obtained using digital optical microscopy (DOM), scanning electron microscopy (SEM), particle size analysis (PSA), and micro CT scanner -image analysis. The optimum objective of this study is to evaluate pigment dispersion in PCs composition, by understanding the relationship between the processing conditions, particle size distribution, and the colour difference output. This will help us in understanding additional dispersion issues that have a bearing on colour variations for different polycarbonate (PCs) compound grades.
