SOLID PHOSPHITE ANTIOXIDANTS: THEIR EFFECT ON PROCESSING AND PRODUCT QUALITY IN LLDPE BLOWN FILM EXTRUSION

摘要

The processability and final physical properties of a film grade LLDPE resin are impacted by the stabilizer formulation used. This paper investigates how different solid phosphite antioxidants can affect processability during the blown film extrusion process and also how stabilizer formulation and processing affect the physical properties of the film. LLDPE resins from two different manufacturing sources were evaluated to determine the effect of these parameters.
