Black Masterbatch is a high-performance, carbon black–based concentrate used to impart deep black color, UV protection, and opacity to plastic products. It consists of fine carbon black particles uniformly dispersed in a compatible polymer carrier, enhanced with specific additives for superior dispersion, stability, and processing performance.
It is widely used in extrusion, molding, and compounding applications across multiple industries.
Key Features
- High jetness and deep black coloration
- Excellent dispersion and surface finish
- UV protection and weather resistance
- Thermal stability during high-speed processing
- Compatible with various polymers: PE, PP, PS, PET, ABS, PA, etc.
- Grades available for food-contact and outdoor applications
- Improves opacity and product durability
- Customizable formulations upon request
