A majority of the plastics manufacturing operations are dependent on the formability of the molten thermoplastics. Ability of the material to flow at a set temperature influences the formability and the overall polymer melt process. Lubricating additive technologies are being developed to engineer the melt flow performance of the resin, promoting the compounding and molding process such as to reduce torque on the motor, reduced shear degradations, enhance uniform filling of hard-to-fill section, promoting thin wall molding, and influence the overall cycle time. Various lubricants are used in formulations to supplement superior flow and metal release with minimal effect on mechanical properties.This paper discusses the methodology to characterize the effectiveness of melt flow additives through comparing two different processing aids in Polybutylene terephthalate (PBT) polyester filled and unfilled matrix and imply differences in processing. The learning from findings in this paper can be adapted to other resin systems as applicable.
