CA® – Aid

CA® – Aid masterbatches contain special-based Polymer Processing Additives. Because of the incompatibility of this additive with the plastics and the high affinity for the metal, a thin coating is formed in the extruder die. The friction between the molten plastic and the metal die-wall reduces, resulting in a reduced stress on the plastic. This eliminates the melt fracture during the extrusion of (m)LLDPE rich blends at high shear rates (output rates). The head pressure reduces. The production can be optimized. The films have a higher gloss.

In addition CA® – Aid products used in PE, PP, PS, … will minimize any die lip build-up. Less stops will be required for cleaning of the die lips, resulting in a higher productivity, thus reduced cost.

The coating prevents the plastic to remain

Typical Benefits by using CA® – Aid:

  • Elimination of melt fracture in (m) LLDPE
  • Reduce operating pressures
  • Increase output
  • Higher levels of LLDPE in LDPE blending
  • Better mechanical properties
  • Down gauging
  • Improve processing of lower MI resins
  • Extrusion through narrower die gaps
  • Less machine direction drawing
  • Better balance of properties
  • More efficient cooling –> better optical properties
  • Improved gauge control
  • Reduce Die Build-up: Longer run-times in between cleaning stops
  • Reduction in gel formation during extrusion
  • Faster color change
  • Increase gloss and improve surface smoothness
  • Reduce variations in thickness profile
