What is black masterbatch?
Black masterbatch is a concentrate with a high loading of carbon black dispersed in a carrier polymer. It gives plastics a deep black color and full opacity. Because carbon black absorbs UV radiation, it also protects the polymer from sunlight in outdoor products. Black masterbatch is one of Erk-Han's three export-focused core product groups.
Why dispersion matters
The result you get from carbon black depends on its particle size and how well it is dispersed in the melt. Agglomerated carbon causes holes and breaks in film and mechanical weakness in pipe. Our formulations use highly dispersible carbon black grades; P-type carbon blacks can also be selected for pipe and outdoor applications. The goal is a more uniform color and higher tensile and tear strength at the same ratio.
Concentration options
- 20% - 30% carbon: An economical option for general injection molding and standard film applications.
- 40% - 50% carbon: For high UV resistance, thin film and applications that need full opacity.
The carrier polymer is selected for your process (extrusion, injection, blow molding) and your base polymer: PE, PP, PS, ABS or PC.
Main end uses
- Infrastructure and pipe: Corrugated pipe, PE drinking water and natural gas pipe, drip irrigation pipe.
- Automotive: Interior and exterior trim parts, under-hood covers.
- Packaging and film: Industrial packaging, mulch film, garbage bags.
- Cable and electronics: Cable jackets and insulation housings.
