Black masterbatches are high concentrations of carbon black, typically 15 - 50% dispersed in thermoplastic resins which act as a carrier or binder. Masterbatches and concentrates allow plastic processors to utilize carbon black and other dry powders in a pre-dispersed pellet form, allowing easy incorporation in extrusion and molding processes. These masterbatches are then incorporated into various polymers to impart properties such as color, UV resistance, and electrical or thermal conductivity.
Carbon Black Masterbatch can be produced in almost any thermoplastic resin; however the most common resins tend to be polyolefins, styrenics, and engineering resins such as polycarbonate and nylon.
