Product Description
HJR 389 is a rutile titanium dioxide pigment produced via the sulfate process. Its hydrolysis and calcination stages are specifically designed and controlled, followed by refined milling, resulting in small particle size and a favorable particle size distribution. Treated with inorganic alumina coating and specialized organic surface modification, it serves as an excellent plastic-grade white pigment.
Main Features
- Extremely strong hydrophobicity
- Blue undertone
- Low oil absorption
- High tinting strength
- Low volatility, low viscosity, and excellent processing flowability
Applicable scope
- Suitable for use in polyethylene, color masterbatch, PVC, ABS, and other plastic industries
