The pigment dispersibility refers to the process of pigmentary dispersion ability, it is an important indicator in coloring plastic. Because most of the plastic manufacturers use melt extrusion process, which means small shear force compared with the ink process by roll mill and coating process by sand grind.
The pigment dispersibility will not only affect the tinting strength and shade, but also the coloring appearance(uneven color, streak and inclusions) and mechanical properties of the final products. A pigment with good dispersibility will lead an ideal vividness, brightness, transparency plastic products. So the pigment dispersibility makes important significance for coloring plastic.
The pigment dispersion is extremely important in fiber spinning. A poor pigment dispersibility will lead high melt pressure to block the the filter frequently, waste raw material and labor, long time equipment parking, even production stop.................complete text
