But in fact I could not find all the excellent colorant, only for different purposes to consider the different sides. For example, plastic parts like a decoration to meet the color requirements of the main aspects; plastic components for industrial coloring agents focused on products to consider the impact the physical and mechanical properties; hollow container focus on the chemical stability of the coloring agent, not with the Sheng Items action; focus on food packaging materials such tasteless hygiene requirements. Use dye coloring, since pigment powder evenly distributed in colored resin needed, so its good distribution of fertilizer anti-caking colorant products, this conclusion can only bear coloring agents for plastic products sales of fertilizer defense, especially thick-walled products words, for blown film, spinning products is another matter. Because the toner is generally not been pretreated fertilizer anti-caking colorants, when mixed with the resin after it alone from the extruder feed, screw, to spout such a distance and in such a short time mixed plastics fertilizer anti-caking colorants manufacturer, to make pigment powder pigment molecules and colored molecules join hands well - fully integrated, completely can not guarantee there will be "cooked" phenomenon. However, this "cooked" phenomenon in the thick product will be masked out, blown film, spinning products is obvious. So which method is still colored masterbatch based.
