Masterbatch on the color used is a certain requirement, the following with us to see the color of Masterbatch on the selection of Masterbatch bar!

(1) Should understand the other properties of the pigment, such as plastic products used in food, children's toys, the pigment should be non-toxic; plastic products used in electrical appliances, should choose good electrical insulation color; for outdoor plastic products, should choose good weather aging resistance color.

(2) the dispersion and coloring power of the pigment should be good. The appearance performance of the product will be affected when the pigment disperses unevenly, and the dosage of the pigment will be increased and the material cost will be increased when the dyeing force is poor. The dispersion and dyeing power of the same pigment in different resins are not the same, so we should pay attention to this point in selecting the pigment; the particle size of the pigment is also related to the dispersion, the smaller the particle size of the pigment, the better the dispersion and the stronger the dyeing power.

(3) The pigment can not react with resin and various auxiliaries. It has strong solvent resistance, low mobility and good heat resistance. That is to say, color masterbatch can not participate in all kinds of chemical reactions. For example, carbon black can control the curing reaction of polyester plastics, so carbon black can not be added to polyester; because plastic products molding processing temperature is higher, so the pigment should not decompose and discolor in the molding heating temperature conditions, generally inorganic pigments have better heat resistance, organic pigments and dyes have poor heat resistance, this should be in the choice of colors Enough attention should be paid to varieties.
