Milliken claims to have overcome one of the toughest challenges in the plastics industry – successful nucleation of polyethylene (PE).
The company says its Hyperform HPN-20E nucleation agent ‘enables higher peak crystallization temperatures that can cut cycle times and drive productivity improvements of 10-20% (depending upon processing and resin design). It can also increase oxygen and water vapour barrier performance between 20-40% (depending upon processing and resin design), providing the possibility of extended shelf life of perishable contents such as dry foods, dairy products, vitamins and nutraceuticals.
This technology is appropriate for high-density polyethylene (HDPE) used in blown film, extrusion blow moulding and injection moulding, as well as in linear low density PE (LLDPE), especially C4 gas phase LLDPE.
