What Is Black PE Masterbatch and Applications?
1. What is Black PE Masterbatch?
Black PE Masterbatch is a type of black color concentrate produced by dispersing black pigment powder (usually Carbon Black) into a PE (Polyethylene) carrier resin, combined with dispersing agents and thermal stabilizers.
This product provides deep black color, excellent coverage, color stability, and easy compatibility with PE-based plastics and some other polymers.
Main components:
- Pigment: Carbon Black (CB) – 30–50% depending on grade
Carbon Black is an ultra-fine black powder produced by incomplete combustion of carbon-containing materials such as petroleum, natural gas, or coal. It is the most important black pigment and is widely used in plastics, rubber, paints, and inks.
Carbon Black has extremely small particle size, typically 10–80 nanometers, and a large surface area, which helps produce deep black color with excellent coverage. Carbon Black determines 70–80% of the quality of Black PE Masterbatch, directly affecting blackness, dispersibility, UV resistance, and production cost of the final product. - Carrier resin: LDPE / LLDPE / HDPE
In producing Black PE, choosing the right carrier resin is crucial because it determines compatibility, dispersibility of Carbon Black, and the final quality of the plastic product. - Additives: dispersing agents, thermal stabilizers, antioxidants
In addition to carrier resin and Carbon Black, additives play a vital role in ensuring consistent quality, ease of use, and long-lasting performance. They ensure uniform color, durability, and easy processing while optimizing production efficiency and cost. These additives are key factors for the success of masterbatch products in the market.
Key characteristics:
- Deep black color with high blackness and gloss
- Excellent dispersion with no black specks
- Good heat resistance during processing
- Long-term color stability under environmental exposure
- Easy to mix and compatible with a wide range of applications
2. Advantages
- High coloring efficiency: Low dosage (1–5%) achieves deep black color
- Reduced production cost: Replaces loose pigment, reduces waste, and optimizes processes
- Clean and safe: Easy to handle and store, minimizes dust
- Enhanced product performance: Some Black PE grades offer UV resistance and improved outdoor durability
