Plastic products mainstream colorant - color masterbatch, how to choose？

1. Generally, for the purchase of color masterbatch, the supplier should be informed of the required color, application field and application requirements, and the supplier should design the formula and process according to the requirements, and finally produce a color masterbatch product that meets the needs. When it comes to formula design, it is necessary to understand the composition of the color masterbatch, which is mainly divided into the following basic elements:

Colorants, organic/inorganic pigments such as titanium dioxide, carbon black, etc., also provide special effects of pigments, such as pearlescent pigments, metal pigments, etc.

Dispersion lubricant, improve the dispersion of pigment in the process of production, such as polyethylene wax, polypropylene wax, etc.

(3) The carrier resin is the pigment evenly dispersed and stable carrier, so that the masterbatch products appear granular state; Thermoplastic resins such as polyolefin resins (PE, PP), polyvinyl chloride, ABS, PET, and thermoplastic elastomers such as propylene - vinyl copolymer elastomers (POP), etc., can become the carrier resin of color masterbatch; General selection and products similar to the resin type.

(4) additives/additives, can be divided into process additives and functional additives;

- Process additives to help improve the smoothness of the process such as antioxidants, lubricants, etc.;

- Functional auxiliaries, used to give or improve the properties of products, such as antistatic agents, flame retardants, antibacterial agents, etc.
