Key Features and Advantages
1. Superior Opacity and Whiteness
R-248 delivers high hiding power and brightness, ensuring optimal color coverage and vibrant appearance in plastics. This reduces the amount of pigment required while maintaining color consistency.
2. Excellent Dispersibility
Thanks to its alumina surface treatment and controlled particle size, R-248 disperses easily in polymers such as PE, PP, PS, ABS, and PVC, minimizing agglomeration and enhancing production efficiency.
3. UV and Heat Stability
R-248 is engineered for thermal and UV resistance, making it suitable for both indoor and outdoor plastic applications. It helps prevent yellowing and degradation when plastics are exposed to sunlight or processing temperatures.
4. Low Oil Absorption
The low oil absorption rate of R-248 allows for better processing flow, making it ideal for high-speed extrusion, injection molding, and film blowing applications.
