Abstract Types of nucleating agents and their dosage level play an important role on the crystallinity of
the polymer which controls the final properties like optical clarity, stiffness and reduced cycle
time during molding. In this study, the efficiency of two different types of commercially available
nucleating agents, phosphate ester and dicarboxylic acid based, have been studied. Both the
nucleating agents were compounded with molding grade polypropylene homopolymer having
melt flow index (MFI) of 12 g/10min at 2.16 Kg and 230°C, in a co-rotating twin screw extruder at
two different dosage level, i.e. 300 ppm and 600 ppm. The effectiveness of… More >
