Masterbatch production starts with selecting raw materials. The base carrier resin must match the polymer used in the final product. Common carriers include polyethylene (PE), polypropylene (PP), and polystyrene (PS). Pigments, additives, or fillers are then chosen based on desired properties like color, UV resistance, or flame retardancy.
Formulation involves precise blending of these ingredients. The right ratio ensures even dispersion and maintains polymer performance. For example, color masterbatch typically contains 20-60% pigment, depending on intensity needed. Additives usually range from 5-30%. Achieving a balanced formula prevents issues like poor flow or surface defects.
The main production method is extrusion. Ingredients feed into an extruder, where heat and shear mix them thoroughly. Twin-screw extruders are preferred due to superior mixing and dispersion capabilities. The molten mixture then cools and forms pellets or granules.
Key steps in extrusion include:
Feeding: Raw materials metered into the extruder.
Melting: Heat softens carrier resin.
Mixing: Screws blend additives uniformly.
Shaping: Melted mass extruded through a die.
Cooling: Solidified on cooling belts or water baths.
Pelletizing: Cut into uniform pellets for easy handling.
Alternative methods like injection molding or batch mixing exist but are less common for masterbatch.
Quality control ensures masterbatch meets performance and safety standards. Tests focus on:
Color consistency: Measured with spectrophotometers.
Dispersion: Microscopic analysis checks pigment distribution.
Melt flow index (MFI): Assesses flow properties during processing.
