Masterbatch with pigment requirement

Masterbatch pigment used , care must be taken with the relationship between pigment and plastic raw materials , additives between points below their choice .
( 1 ) pigment can not be reactive resins and various additives , solvent resistance, migration of small , photoluminescent paint suppliers resistance and so on. That is, the masterbatch can not participate in a variety of chemical reactions. Such as carbon black can control the curing reaction of polyester plastic , so you can not add carbon black pigment in the polyester .
Due to the high temperature plastic molding process , so should not break down color pigment in molding the heating temperature conditions. General inorganic pigments good heat resistance , poor heat resistance of organic pigments and dyes , this should be taken seriously enough variety in the choice of pigment .

( 2 ) dispersion of the pigment should be a good coloring power . When pigment dispersed unevenly , it will affect the appearance of the performance of products ; pigment tinting strength is poor, will increase the amount of pigment material costs increased. The same pigment dispersion in various resins and color strength are photoluminescent pigment suppliers, so pay attention when choosing this pigment .
The toner particle size and dispersibility of the relationship , the smaller toner particle size , the better the dispersibility , the coloring power is strong.
( 3 ) should be aware of other pigment properties, such as for use in food , children's toys aspects of plastic products, the requirements should be non-toxic pigment ; for electrical aspects of plastic products, electrical insulation should choose good pigment ; plastic products for outdoor areas , should choose a good resistance to weathering properties of pigment and so on.
