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.
