Nucleation has traditionally been used to improve physical properties of polypropylene. Recently it has evolved to offer many more benefits including cycle time reduction,
warpage improvements,
dimensional control,
barrier enhancements and
improved aesthetics. Nucleation has also expanded into polyethylene.
Nucleation of polyethylene has been studied over the years, but until recently, was never commercially utilized due to mediocre performance enhancement achieved with technologies typically designed for PP. A new material, Hyperform® HPN-20E shows breakthrough performance in polyethylene nucleation and offers exciting enhancements in optical, physical, processing, barrier and seal properties of different polyethylenes.

Nucleation technologies can be categorized into three areas: conventional, advanced and hyper nucleation. hyper nucleating agents are the most recently developed and offer processors and users the combined benefits of high crystallization rates and isotropic shrinkage control which lead to improved production and part quality performance, in addition to the traditional mechanical property-related enhancements.
Hyper nucleation technologies can also be combined to find the appropriate balance of dimensions and properties. Thus, this newest class of hyper nucleation technologies combines the main benefits of traditional nucleators whilst further optimizing performance and thus broadening the use window of polypropylene and polyethylene.
