What is masterbatch? Whats it for?

Masterbatch coloring is a new kind of polymer material, the excellent performance of coloring, energy saving, no dust and is widely used in polyethylene, polypropylene, polystyrene, ABS, nylon, PC, PMMA, PET resin, production out of the colored fiber, clothing, daily plastic, wire and cable, home appliances, agricultural film, auto parts and other products.

Master batch is composed of excessive chemical additives, carrier resins and dispersants. Masterbatch is the constant pigment (dyestuff) uniformly loaded in the resin to get the aggregate. Masterbatch is mainly composed of pigment, dispersant and carrier resin.

Color master batch technology is very strict process requirements, generally adopted color master batch technology is wet process. Color master batch material by water phase grinding, phase transfer, washing, drying, granulation, only in this way the product quality is good. In addition, the pigment in the grinding process at the same time, should also carry out a series of masterbatch technology detection, such as the determination of sanding grout fineness, determination of sanding grout diffusion performance, determination of sanding grout solid content and determination of paste fineness and other items.

Six benefits of using masterbatch:

1. Make the pigment have good dispersibility in the product. In the process of masterbatch production, it is necessary to refine the pigment to increase the dispersibility and coloring power of the pigment. The carrier of color masterbatch is the same as the plastic of the product, with good matching, and the pigment particles can be well dispersed in the plastic of the product after heating and melting.

2. It is beneficial to maintain the chemical stability of pigments directly use of pigments, because in the process of storage and use of pigments directly contact air, pigments will occur water absorption, oxidation and other phenomena, and do color mother, because the resin carrier will be pigments and air, water isolation, can make the quality of pigments for a long time the same.

3. The stable color master particle of the product color is similar to the resin particle, which is more convenient and accurate in the measurement. It will not adhere to the container when mixing, and the mixing with the resin is also more uniform, so it can add the stability of the amount, and the stability of the product color.

4. Protection of operator's health Pigments are generally powdery, adding and mixing easy to fly, will affect the health of operators after being inhaled by the human body.

5. Keep your environment clean.

6. Easy to use: due to the color masterbatch and resin particles similar shape, so in the measurement is more convenient and accurate, mixing will not adhere to the container, so it saves the time to clean the container and machine and the raw materials used by the cleaning machine. Application range of masterbatch: widely used in polyethylene, polypropylene, polystyrene, ABS, nylon, PC, PMMA, PET and other resins, the production of colorful fiber, clothing, daily plastics, wire and cable, household appliances, agricultural film, auto parts, health care equipment and other products.
