4. Application

Color master batch is also known as color seed. It is a new type of special colorant for polymer materials, it’s also called pigment preparation. Color masterbatch is mainly used in plastics. Color masterbatch is composed of pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super constant pigment into resin. It can be called pigment concentration, so its coloring power is higher than pigment itself. When processing, a small amount of color masterbatch and uncolored resin can be mixed to achieve the design pigment concentration of colored resin or products. In order to make the pigment have better dispersion in the products, it is necessary to refine the pigment in the production process to improve the dispersion and coloring power of the pigment. The carrier of the special color masterbatch is the same as that of the plastic products, which has good matching. After heating and melting, the pigment particles can be well dispersed in the plastic products.

Optical brightener agent OB-1 is a kind of optical brightener for plastics, it’s a widely used optical brightener for polymer. It’s also a good optical brightener for PVC masterbatch. OB-1 can be refined in the production process of PVC masterbatch to improve the dispersion and coloring power of the optical brightener. The carrier of the PVC masterbatch is the same as that of the PVC products, which has good matching. After heating and melting, the OB-1 particles can be well dispersed in the plastic products.

FQA
