What Is White Masterbatch?

White masterbatch is a concentrated mixture of titanium dioxide (TiO₂), polymer carrier resin and functional additives. It is supplied in pellet form and is added directly during plastic processing to produce bright, uniform white products.

Compared with using titanium dioxide powder directly, white masterbatch offers:

  • Better pigment dispersion

  • Cleaner production

  • Accurate dosing

  • Stable color consistency

  • Improved processing efficiency

Advantages of White Masterbatch

Excellent Whiteness

High-quality titanium dioxide provides bright, clean and consistent white color.

High Opacity

White masterbatch effectively hides the natural color of plastic resins, producing excellent coverage.

Superior Dispersion

Even distribution of pigments helps eliminate streaks, spots and uneven coloration.

Stable Processing Performance

Suitable for high-speed production with consistent coloring performance.

Cost-Effective Production

Easy dosing and reduced material waste help lower manufacturing costs.

Common Applications

White masterbatch is widely used in:

  • Plastic packaging

  • Food containers

  • Household products

  • Plastic bottles

  • Films

  • Pipes

  • Sheets

  • Injection molded products

  • Blow molded containers

  • Electrical components

How to Choose the Right White Masterbatch

When selecting white masterbatch, consider these key factors:

Titanium Dioxide Content

Higher TiO₂ content generally provides better whiteness and opacity.
