EFFECT OF THE MASTERBATCH CARRIER ON THE PIGMENT DISPERSION AND MECHANICAL PROPERTIES OF COLORED POLYOLEFINS

摘要

Polyethylene and polybutene were used as carriers to produce two color concentrates with a high amount of organic pigments. Different colored plastic products, namely polyethylene film and polypropylene injection molded parts, were produced using both masterbatches. The polybutene masterbatch promotes a better dispersion of the pigment and improves the toughness of injection molded polypropylene.
