Pellets comprising pigment dispersed in an ethylene-vinyl acetate polymer

摘要

Colour concentrate pellets for pigmenting polyvinyl chloride are substantially all of diameter 0.1 to 3mm and comprise pigment dispersed in a carrier comprising ethylene-vinyl acetate polymer which is ethylene-vinyl acetate copolymer and/or alloy thereof with polyethylene, the polymer having a vinyl acetate content of 13-28% by weight and a melt flow index (as measured by the method of ASTM D1238 using a 2.16kg weight at 190 DEG C) of 3.5-150g/10 minutes, the pellets comprising at least 30% by weight of the pigment and at least 10% by weight of the polymer.
