Color materials used in plastic masterbatch must pay attention to the matching relationship between the colorant and the plastic raw material, the auxiliary agent, which is selected as described below.

1) The dispersibility of the color is good. When the color dispersion is uneven, it will affect the appearance of the article; when the color is colored, the amount of color is increased, and the material cost is improved. The same color is not the same in different resins, so it should be aware of this when selecting the color. The particle size and dispersibility of the color are also related, the smaller the particle size of the color, and the better the dispersibility, and the color strength is also strong.

2) Color materials cannot be reacted with resins and various auxiliaries, solvent resistance, small mobility, good heat resistance. That is, the plastic master cannot participate in various chemical reactions. Such as carbon black can control the curing reaction of the polyester plastic, so the carbon black material cannot be added to the polyester. Since the molding temperature of the plastic product is high, the color should not decompose discoloration under molding heating temperatures. Generally, the inorganic pigment is well heat resistance, the organic pigment and dye are poorly heat resistance, which should cause sufficient attention when selecting the color species.

3) About the other properties of the color, such as for plastic products used in food, children's toys, plastics, plastic products for electrical appliances, should choose electric insulating color; Outdoor plastic products should be selected from color-protected color aging.

Plastic masterbatch

The plastic masterbatch is made of a high proportion of additives and pigments or thermoplastic resins, and the plastic color slurry has good dispersibility, and the resin used has good wettability and dispersibility, the colorant and the coloring material have good phases. Capacity. That is: the coating + carrier + additive masterbatch.

Plastic masterbatch is a colorant, typically, when a thermoplastic article is produced, different colors can be added as needed. Different materials and different colors are different.What is the main color?is a colorant, typically, when a thermoplastic article is produced, different colors can be added as needed. Different materials and different colors are different.

1) Coloring ability of titanium dioxide: Determination of titanium dioxide in the color of the same plastic product;

2) Titanium white: Light (white) plastic product The appearance of titanium dioxide determines the same content of titanium dioxide;

3) Dispersion of titanium dioxide: The production cost of the column particles and the appearance and gloss of plastic products;

4) Processing performance: The effect of titanium white powder masterbatch production costs.
