white, black, and colored masterbatch
The difference between white, black, and colored masterbatch lies primarily in their composition, colorants used, and typical applications:
  1. White Masterbatch:

  • Uses titanium dioxide (TiO₂) as the core pigment, providing exceptional brightness, high reflectivity, and opacity.

  • Enhances whiteness and ensures uniform white coloration in plastics, often used in packaging, household goods, automotive parts, and construction.

  • Offers UV protection, thermal stability, and can improve product durability, especially for outdoor applications.

  • Compatible with various polymers like PE, PP, ABS, PET, and PVC.

  • Cost-effective for achieving bright and opaque white color; helps reduce production waste and improves processing efficiency.

  1. Black Masterbatch:

  • Contains carbon black, a fine black pigment known for deep color, excellent UV absorption, and electrical conductivity.

  • Provides UV protection and durability, making it ideal for automotive parts, packaging, and agricultural films.

  • Offers a sleek, modern appearance.

  • Requires less pigment for full opacity compared to other colors because of carbon black’s efficiency.

  1. Colored Masterbatch:

  • Composed of various pigments combined with a carrier resin to impart a wide range of colors.

  • Used to add various vibrant colors to plastics in industrial components, appliances, packaging, and consumer goods.

  • Custom-formulated to achieve specific shades and may include additives for UV resistance or other performance enhancements.

In summary:

  • White masterbatch is selected for brightness, opacity, and UV resistance with titanium dioxide as the pigment.

  • Black masterbatch provides strong UV protection, deep color, and heat absorption with carbon black as the pigment.

  • Colored masterbatch covers all other colors and is customizable for desired hues and properties.

Each type caters to different aesthetic and functional requirements in plastic manufacturing.
