What is masterbatch?

A: Masterbatch = Pigment + Carrier + Additive. In general, the carrier is a thermoplastic resin, the toner has a good wetting and dispersion, and has a good compatibility, masterbatch is currently the most common plastic coloring method.

Pigment or dye

Pigments are divided into organic pigments and inorganic pigments, commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, light red, macromolecule red, macromolecule yellow, permanent yellow, permanent purple, azo Red and so on. Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow and so on.

2. carrier

Is the matrix of masterbatch. Special color masterbatch generally choose the resin with the same resin as the carrier, the compatibility of the two best, but also consider the carrier of mobility.

3. Dispersant

So that the pigment is evenly dispersed and no longer agglomerate, the melting point of the dispersant should be lower than the resin, and the resin has good compatibility, and the pigment has a good affinity. The most commonly used dispersant is: polyethylene low molecular weight wax, stearate and so on.

4. Additives

Such as fire-retardant, brightening, anti-bacterial, anti-static, anti-oxidation and other varieties, unless the customer request, under normal circumstances the masterbatch does not contain the above additives.

Classification of masterbatch

By carrier classification: such as PE Color Masterbatch, PP Color Masterbatch, ABS Color Masterbatch, PVC Color Masterbatch, EVA Color Masterbatch and so on

According to the use of classification: such as injection masterbatch, blow molding masterbatch, spinning masterbatch and so on. The varieties can be divided into different grades, such as:

1. Advanced injection of color masterbatch

For cosmetics boxes, toys, electrical enclosures and other advanced products.

2. Normal injection of color masterbatch

For general household plastic products, industrial containers and so on.

3. Advanced blown film masterbatch

For blow molding of ultra-thin products.

4. ordinary blown film color masterbatch

For general bags, woven bags of blow molding coloring.

5. Spray color masterbatch

For textile fiber spinning coloring, color masterbatch pigment fine, high concentration, strong coloring, heat resistance, good light resistance.

6. Low color masterbatch

Used in the manufacture of low-quality color requirements of low-level products, such as trash, low-level containers.

The characteristics of masterbatch

So that there is a better dispersion

Colorants in the production process to be refined on the paint to improve the pigment dispersion and color strength. The carrier of the special color masterbatch is the same as the plastic variety of the product, and has good matching. The pigment particles can be well dispersed in the plastic of the product after heating and melting.

Conducive to maintaining the chemical stability of the pigment

Protect the health of the operator

Pigments are generally powdery, add and mix easily when flying, the body will be inhaled after the impact of the health of the operator.
To ensure the stability of the product color

Color Masterbatch particles and resin particles similar to the measurement is more convenient and accurate, the mixture will not adhere to the container, and the resin mixture is more uniform, so you can ensure the stability of the added amount, so as to ensure the stability of the product color.

Keep the environment clean and easy to use

With the continuous improvement of China's economy in the international status, plastic products processing industry in the domestic fierce development, many enterprises to establish cooperation with international enterprises, the export of color products increasingly demanding, masterbatch gradually dominated.

Introduced so many masterbatch knowledge, Xiaobian believe that we have a deeper understanding of the masterbatch. If you feel helpful, please remember to share Oh!
