Key features of plastic black masterbatch include:
-
High blackness and brightness providing a deep, rich black color, often with high gloss.
-
Excellent dispersion of carbon black in the plastic matrix, ensuring uniform color without spots or streaks.
-
UV resistance and protection against degradation, which enhances the durability of the plastic products.
-
Stable color performance under varying production conditions.
-
Suitable for various plastic processing methods such as injection molding, blow molding, extrusion, and film blowing.
Typical formulations include carbon black content with carriers like HDPE, LLDPE, or PP and additives such as polyethylene wax and processing aids. The black masterbatch is usually supplied in pellet form and packaged in 25 kg bags.
Applications range widely across industries, including automotive parts, electronics, packaging, construction, and household goods due to its coloring, protective, and functional properties.
The production process involves mixing carbon black powder, resin, and additives, followed by high-speed mixing and extrusion, then pelletization.
Overall, plastic black masterbatch is essential for adding color and enhancing the physical properties of black plastic products in industrial manufacturing.
