What should be paid attention to when choosing PP masterbatch?

 

(1) Other properties of colorants should be understood. For example, for plastic products used in food and children's toys, colorants should be non-toxic. For plastic products used in electrical appli

ances, colorants with good electrical insulation properties should be selected. For outdoor plastic products, colorants with good weathering resistance should be selected.

 

(2) The dispersibility and tinting power of the colorant should be good. When the colorant is not uniformly dispersed, it will affect the appearance performance of the product; when the coloring power

of the colorant is poor, the amount of colorant will increase, and the material cost will increase. The dispersibility and tinting power of the same colorant in different resins are not the same, so

you should pay attention to this when choosing a colorant; the particle size of the colorant is also related to the dispersibility. The smaller the particle size of the colorant, the better the disper
