Pangang CR-340 is a high-performance rutile TiO₂ pigment produced by the chloride process, delivering outstanding purity, high brightness, and strong thermal stability. Its surface is treated with a specialized composite coating consisting of inorganic alumina and organic modifiers, which significantly improves dispersibility and compatibility in various polymer systems. As a result, CR-340 is recognized as a premium plastic-grade titanium dioxide pigment, engineered to provide superior whiteness, excellent opacity, and stable processing performance across demanding plastic applications.

Product Features

  • High Opacity & Tinting Strength:  Pangang CR-340 titanium dioxide provides excellent coverage of base materials and enhances color uniformity in plastics.
  • Superior Whiteness & Brightness: Delivers a clean, pure white appearance suitable for aesthetic applications.
  • Excellent Dispersibility: TiO₂ CR-340 ensures uniform distribution in polymer melts, minimizing agglomeration during compounding and extrusion.
  • Thermal & Environmental Stability: Resistant to heat, light, and processing conditions; maintains performance in thin films, extrusion, and molded products.
  • Plastic Compatibility: The coated surface ensures good adhesion and stability in polyolefins, PVC, elastomers, and engineering plastics, enhancing processing efficiency and product quality.

Recommended Applications of Pangang CR-340

Titanium dioxide CR-340 is widely used in plastic and polymer applications requiring high whiteness, opacity, and stability:

  • Polyolefin Masterbatches – Color concentrates and fillers.
  • Films & Extrusion Coatings – High-opacity packaging films and protective coatings.
  • Engineering Plastics – Polypropylene, polyethylene, ABS, and other specialty polymers.
  • PVC Products – Rigid and flexible pipes, profiles, sheets, and fittings.
  • Flooring & Decorative Materials – Linoleum, rubber flooring, and other polymer-based surfaces.
  • Other High-Whiteness Plastic Applications – Wherever uniform color, opacity, and durability are required.

Packaging and Storage

  • Packaging: Typically supplied in 25 kg bags; also available in 500kg or 1000kg bulk bags for industrial users.
  • Storage: Store in a dry, cool, and well-ventilated place. Protect from moisture, direct sunlight, and extreme temperatures to preserve coating integrity and maintain product performance.
  • Handling Precautions: Avoid dust inhalation and prolonged exposure; use standard industrial safety measures when handling powders.
