HOW FUSION IS PROMOTED BY PROCESS AIDS?

2022-07-29

ntroduction:

Process aids (PA) are unique additives that dramatically improve the processability of PVC, at relatively lower concentration.

Besides, they are used to achieve processing improvements, higher productivity, and better product quality.

Nature of process aids:

Process aids are random copolymers, whose major component is methyl methacrylate. Other component may be styrene or acrylonitrile. They are PVC compatible.

Process aids are produced by emulsion polymerization.

Processing aids have two categories –

1. That promotes fusion and adds rubber elasticity during processing, and

2. That adds lubricity during processing.

Processing Aids that promotes fusion –

They are acrylic polymer, high molecular weight MMA copolymers (MMA / styrene) or Acrylonitrile styrene.

Modified rheology (Viscosity & Elasticity) and morphology (how primary particles arrange – fuse together) of PVC compound during processing is a function of molecular weight of process aid.
