Polymer Processing Aids masterbatches

Our Polymer Processing AID grades are dedicated to Polyethylene, Polypropylene and TPV productions.

The mechanism

WHY ?

Issue #1:

Increasing throughput → friction between the metallic barrel walls and the resin material being processed

Consequences:

  • Increase Pressure inside the barrel
  • Resin being stressed and facing high shear
  • Melt fracture, Hair angel Shark Skin

Issue #2:

  • Critical phenomenon to avoid as long as possible during extrusion
    cycle
  • Build up generated by high internal pressure and filler presence
    wihtin the material can take several hours to form
  • When the agreggates become too massive, stripes and film
    degradation happen

At the exit of the extruder, melt fracture, die build up and polymer degradation will cause gels and black spots presences on the surface of the converted polymer and when the deposit is too important, will force operators to stop the machine for cleaning operation.

HOW ?

During 15/ 20 min, PPA masterbatch is sent at around 15% with the resin
inside the extruder/ barrel.
The additive presents affinity with metal structures It will then coat the barrel and the screw creating a protective layer.

After this time:

  • Pressure Drop will be initiated
  • Melt Fracture will happen at the middle of the drop
  • Pressure will be then stablized

The masterbatch is still used in production at 1-1.5% to continuously regenerate the protective coating layer.
