Performance Characteristics

  • High Whiteness and Bright Bluish Undertone. Titanium dioxide R-213 delivers outstanding whiteness with a clean, slightly bluish tone, enhancing brightness and visual appeal in finished plastic products.
  • Excellent Dispersion and Processability. The optimized surface treatment ensures fast and uniform dispersion in polymer matrices, reducing agglomeration and improving processing efficiency during extrusion and injection molding.
  • Strong Opacity and Tinting Strength. High refractive index and well-controlled particle size distribution provide excellent hiding power and color strength, allowing for efficient pigment usage and cost optimization.
  • Hydrophobic Surface Treatment. The hydrophobic surface minimizes moisture absorption, improves storage stability, and reduces defects such as pinholes or bubbles during high-temperature processing.
  • Low Volatile Content. Low volatility helps prevent processing issues such as odor generation, die buildup, and surface imperfections in plastic products.
  • Regulatory Compliance. TIOXHUA R-213 complies with FDA requirements for food-contact applications, subject to proper formulation and end-use evaluation.
