Color master classification methods are commonly used as follows:
According to carrier classification: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch and other classification according to purpose: such as injection masterbatch, blow masterbatch, spinning masterbatch and other varieties can be divided into Different levels, such as:
1. Advanced injection masterbatch:
For cosmetic packaging, toys, electrical enclosures and other advanced products.
2. Ordinary injection masterbatch:

4. Ordinary blown film masterbatch:
It is used for blow molding of general bags and woven bags.
5. Spinning masterbatch:
It is used for textile fiber spinning coloring. The pigment masterbatch has fine particles, high concentration, strong coloring power, good heat resistance and light resistance.
6. Low grade masterbatch:
It is used to manufacture low-grade products with low requirements on color quality, such as trash cans and low-grade containers.

The heat-resistance grade of the special masterbatch is generally compatible with the plastic used for the product, and it can be used safely at normal temperature. Only in the following circumstances will cause varying degrees of discoloration, one is the temperature exceeds the normal range, one is too long downtime.
9. Masterbatch coloring has the following advantages over granulation coloring:
9.1. Coloring and processing of finished products can be completed at one time, avoiding the coloration of plastics and heating the plastics, which is beneficial to the quality of plastic products.
9.2. Minimize the production process of plastic products.
9.3. Save a lot of energy
