Abstract

This paper describes the effect of nucleating agents on the morphology and crystallization behaviour of polypropylene. Nucleated and un-nucleated grades of polypropylene are compared, and the ability of both titanium dioxide pigment particles and recycled material to nucleate polypropylene is examined. Nucleating agents are found to have a significant effect on crystallization behaviour and titanium dioxide pigment is found to be a relatively efficient nucleating agent at addition levels as low as 0.5%. The consequences of these results for obtaining end product consistency in polypropylene are discussed briefly.
