1. the effect of poor foresight
Color is used for coloring, General masterbatch pigment in different plastics are a different color, thus the predictability of the effect is poor.
2. impact performance of other plastic products
Particular strength, products are easily deformed, twisted, plastic is more obvious.
3. high cost
General master in order to be able to ' universal ', tend to use higher heat levels of pigment, resulting in waste.
