Influence of polymer processing parameters and coloring agents on gloss and color
of acrylonitrile-butadiene-styrene terpolymer moldings (in English)

Polimery 2016, No 7-8, 544

Summary

The results of examination of the influence of polymer processing parameters and addition of coloring agents in the form of yellow organic pigment PY 191 and its masterbatches based on acrylonitrile-butadiene-styrene copolymer (ABS) or polystyrene (PS) on the color and gloss of injection molded parts have been presented. Gloss investigations, at the light incidence on the molding surface in the direction of polymer flow in the cavity and in the opposite direction at an angle of 60° and 20° were made (Figs. 3–6). Color tests were also carried out (Table 4). The obtained results showed that high mold temperature (Tf = 80 °C) and lower injection temperature (Tω = 230 °C) allow to obtain parts of higher gloss and smaller variation in their color.
