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