Description
White masterbatches are pigments and additives dispersed in a carrier resin, used to color plastics white. They are widely used across various industries due to their cost-effectiveness, ease of use, and ability to achieve desired whiteness, opacity, and brightness in plastic products. Here’s a breakdown of the main types of white masterbatches, primarily categorized by their pigment:
- Titanium Dioxide (TiO2) Based White Masterbatches
This is by far the most common and dominant type of white masterbatch. Titanium dioxide is the white pigment of choice due to its:
- Excellent Whiteness and Brightness
- Polyethylene (PE) based: For coloring PE films, blow molded items, injection molded parts.
- Polypropylene (PP) based: For coloring PP films, injection molded parts, fibers.
- Polystyrene (PS) based: For PS packaging, cutlery, housewares.
- PET/PBT based: For PET bottles, films, and engineering plastics.
- ABS based: For ABS applications like appliance housings, automotive interior parts.
- PVC based: For PVC pipes, profiles, cables, flooring.
- Universal or Multi-polymer carrier: These are designed to be compatible with a wider range of polymers, offering flexibility.
- Excellent Whiteness and Brightness
