Key Features and Advantages
1. High Whiteness and Opacity
CR-350 offers excellent hiding power and brightness, making it ideal for use in white and colored plastic formulations. It ensures clean, vivid shades with minimal pigment loading.
2. Excellent Dispersibility in Polymers
Due to its advanced surface treatment, CR-350 disperses uniformly in a wide range of plastic resins, including PE, PP, PVC, ABS, and engineering plastics. This leads to smooth, defect-free surfaces and consistent product quality.
3. Superior UV and Thermal Stability
The rutile structure and high purity of the pigment provide strong resistance to UV radiation and heat, ensuring long-lasting color performance in outdoor plastic products like garden furniture, siding, and pipes.
4. Low Volatility and Low Oil Absorption
Its low oil absorption improves melt flow properties, while its chemical stability under processing temperatures ensures optimal production efficiency and minimal impact on resin behavior.
