Masterbatch is a high concentration of pigment preparations and efficiently. Which uses special processing technology of high concentration uniform and stable pigment dispersed in a carrier resin. In general the main components of masterbatch for coloring agents, dispersing agents, carriers three parts.

Below to find out more about the specific content of a coloring agent, a dispersing agent and carrier:

1. colorants: As the name suggests this is the most important part of masterbatch. Polyolefin (commonly known as soft) using the colorant is a pigment masterbatch. The use according to choose different properties of the different pigments, including organic and inorganic pigments.
Plastic (commonly known as PS) masterbatch can be solvent dyes and organic pigments inorganic pigments and some part of the senior high temperature. Generally not available for polyolefins coloring dye may cause serious migration, if you want to use must be very careful and pay attention to control the dosage.

2. dispersants: Dispersant mainly on the surface of the pigment wetting is conducive to further disperse the pigment and stability in the resin. At the same time it must be good compatibility with the resin, the coloring does not affect product quality. Soft dispersants generally use low molecular polyethylene, zinc stearate and the like. PS masterbatch dispersant generally use polar low molecular weight polyethylene, such as magnesium stearate.

3. Carrier: carrier is evenly distributed pigment masterbatches and grainy. Select a carrier to be considered with the colored resin compatibility, but also consider masterbatch should have good dispersion. Thus the carrier mobility is greater than the colored resin, at the same time after being colored not affect product quality. General carrier resin can be colored resin molecular weight less than similar polymers.

Masterbatch for the special needs of some, its composition and some additives. In order to improve the heat resistance of masterbatch, light fastness can be added antioxidants 1010, DLTP, 264 and so on. In order to improve light resistance masterbatch, anti-aging, anti-UV agents can be added, such as UV531, UV326 and so on.
