Use of Polymer Processing Aids to Reduce Gel Formation in Polyolefin Plastomer Extrusion, 1998 Polymers, Laminations & Coatings Conference Proceedings

Polymer additives have long been linked to gel formation and reduction in polyolefm tihn extrusion. Several hypothesis about these additive/gel links have been empirically explored in a controlled blown film experiment. A study comparing gel levels in a metallocene catalyzed polyolefm plastomer was done on a lab size blown film line with a groove feed extruder. A photo imaging process was used to count gel levels, per unit area, during a significant portion of each run. Additive packages were varied to determine the effect of potential gel reducing additives. The data support the hypothesis that Dynamar TM polymer processing aids can reduce the amount of gel particles in the film.
