Understanding White Masterbatch: A Quick Overview
White masterbatch serves as a concentrated pigment additive that infuses plastics with brilliant whiteness, opacity, and UV protection. Producers incorporate titanium dioxide masterbatch into base resins during extrusion or molding, ensuring uniform color distribution without agglomeration.Core elements include:
- • TiO2 Pigment: The primary whitening agent, available in rutile for superior UV resistance or anatase for cost-effective opacity. Rutile TiO2, with its high refractive index, scatters light effectively, achieving up to 95% opacity in thin films.
- • Carrier Resin: Acts as the binder; PE or PP variants dominate due to their compatibility with common polyolefins.
- • Additives: Include dispersants, stabilizers, and compatibilizers to enhance flow, prevent degradation, and add features like UV stabilized white masterbatch.
