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
