With systems designed for producing masterbatch, Gala can efficiently and economically meet the needs of the masterbatch or color concentrate producer. These products are typically produced in sizes from 1 mm to 3.2 mm. The spherical underwater pelletized masterbatch pellets are free flowing and easily dispersed for better utilization by the end user.

  • Underwater pelletizing of masterbatches used as a concentrated supply of additives and pigments produces very good results, both in standard pellets and in micropellets.
  • Masterbatches are pelletized with virtually all commercial fillers (pigments and other additives or stabilizers).
  • Micropellets = uniform distribution of concentrates in mixing reduces problems in the material supply.
  • In micro-pelletizing, pellet sizes of approx. 0.5 mm are currently possible.  Masterbatch materials for pigments, additives and fillers offer a high level of uniformity at grain sizes of 500 to 1,500 µm.


Masterbatch micropellets offer special advantages since plasticating lengths, mixing behavior and mixing accuracy are significantly improved at reduced extruder lengths.  Low energy requirements, low shearing effort at reduced effective extruder lengths.  Shorter extruder lengths = reduced risk of polymer degradation.  Uniform distribution of concentrates plus larger surface per unit of volume permits shorter plasticating time and more uniform flow of material.  The particular advantage of underwater pelletizing in this field is the round or spherical pellet shape and the resulting free-flowing properties of the product in the subsequent use.   Pellets permit the provision of sensitive fillers in a clean, dust-free and environmentally compatible bond allowing high loads.
