There are several commonly used classification methods for color masterbatch:
Classified by carrier: such as PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc.
Classified by use: such as injection masterbatch, blown color masterbatch, spinning masterbatch, etc.
Each variety can be divided into different levels, such as:
1. Advanced injection masterbatch:
Used in cosmetic packaging boxes, toys, electrical enclosures and other advanced products.
2. Ordinary injection masterbatch:
Used in general daily plastic products, industrial containers, etc.
3. Advanced blown film masterbatch:
Used for blow molding coloring of ultra-thin products.
4. Ordinary blown film masterbatch:
It is used for blow molding coloring of general packaging bags and woven bags.
5. Spinning masterbatch:
It is used for textile fiber spinning and coloring. The color masterbatch pigment has fine particle size, high concentration, strong tinting strength, good heat resistance and light resistance.
6. Low-level masterbatch:
Used to manufacture low-grade products that do not require high color quality, such as trash cans, low-grade containers, etc.
7. Dedicated color masterbatch:
It is a color masterbatch made of the same plastic as the carrier according to the plastic type specified by the user for the product. For example, PP color masterbatch and ABS color masterbatch respectively use PP and ABS as carriers.
Universal color masterbatch: A resin (often a low melting point PE) is also used as a carrier, but it can be applied to the coloration of other resins than its carrier resin.
8. Universal color masterbatch:
The universal color masterbatch is relatively simple and convenient, but has many disadvantages. It is recommended that the user choose a special color masterbatch.
The heat resistance grade of the special color masterbatch is generally compatible with the plastic used for the product, and can be used with confidence at normal temperature. Only in the following cases will cause different degrees of discoloration, first, the temperature is beyond the normal range, first, the downtime is too long.
9. Masterbatch coloring has the following advantages over granulation coloring:
9.1. Coloring and product processing are completed once, avoiding the heating process of granulation coloring on plastics, and is beneficial to the quality of plastic products.
9.2. The production process of plastic products is simplified.
9.3. A lot of power can be saved.
