Performance Advantages of Dongfang R-5568

Excellent Optical Performance: Its high bluish undertone neutralizes the slight yellowish tint in the resin matrix, resulting in a pure, bright white finish. Its strong hiding power reduces the amount of titanium dioxide added, lowering costs and minimizing the impact on the physical and mechanical properties of the finished product.
Excellent Processing Dispersion: A special surface treatment reduces particle agglomeration, enabling rapid and uniform dispersion during plastic mixing and pelletizing, minimizing defects such as white spots and streaks. Its low oil absorption reduces the amount of liquid additives required, lowering melt viscosity, improving processing flow, and reducing internal stress in the finished product.
Excellent Compatibility and Rheological Properties: It bonds tightly with the plastic matrix and other components in the formulation, minimizing interfacial defects. Its stable processing rheological properties facilitate the production of dimensionalally precise, smooth-surfaced products.
Reliable Durability: Its stable rutile crystal structure, combined with its surface coating, delays resin degradation caused by environmental factors like UV rays, extending the product’s lifespan and preserving its pristine appearance. Dongfang R-5568 is suitable for plastic products exposed outdoors or to long-term sunlight.

Main Applications

Plastics Industry. Titanium dioxide R-5568 can be used in polyolefin (PP, PE) products such as injection molded parts, blow molded products, films, fibers, and pipes; PVC products such as profiles, sheets, and wire and cable sheathing; and engineering plastics (ABS, PS, HIPS, etc.) such as appliance housings and automotive interiors. It also serves as the core white pigment in high-quality masterbatches.

Other Industries. R-5568 titanium dioxide can be used in the preparation of leather colorants and some oil-based coating systems, meeting requirements for high whiteness and weather resistance.

Packaging & Storage

Packaging: Common packaging sizes include 25 kg, 500 kg, and 1000 kg, suitable for container transport, allowing businesses of all sizes to choose the right size.
Storage Requirements: Avoid open-air storage, high temperatures, and humidity. Indoor storage is recommended. Follow the “first-in, first-out” principle and stack no more than 20 layers.
