Based on its proprietary Borstar® technology, Borealis has developed a nucleating approach resulting from its own research – Borstar® Nucleation Technology. The nucleating effect is obtained in the polymerisation reactor (in situ) during the manufacture of polypropylene (PP). This is in contrast to the standard approach of adding a nucleating agent during pelletisation. Borstar Nucleation Technology has a number of advantages compared with conventional nucleation:

Borstar Nucleation Technology-based PP demonstrates benefits in a range of applications with the Borealis portfolio of high-performance PP homopolymers and heterophasic polymers for thin wall packaging, automotive, and sewage pipe segments.
The improved stiffness of these materials allows for lower wall thicknesses, enabling downgauging of the end product. Furthermore, this solution enables significant reduction in cycle time, helping moulding customers improve their resource efficiency and reduce their carbon footprint, adding value to the end product for brand owners.
For converters, Borstar Nucleation Technology enables more efficiency and sustainability in production through:
