Evaluation of the homogenization properties of masterbatches

Appearance is a very important property for many different products, therefore it is important to investigate what types of parameters and processing conditions influence their appearance. The proper investigation of this property requires a reliable and repeatable measurement method. Recently, a novel evaluation method has been developed to evaluate the colour inhomogeneity of injection molded specimens. In this study, this novel inhomogeneity evaluation method was used to compare the homogenization properties of different masterbatches. It was shown using this technique that the homogenization properties of different masterbatch recipes can be evaluated and developed. The results of this method were validated by a group of trained technicians and their results were correlated with the inhomogeneity levels derived from the new method.
