The most widely consumed plastic material in the world is polyolefins. Throughout the years, polypropylene has been modified through nucleation. This has been especially important to achieve clarification and to improve optical and physical properties, warpage control and processing speed.
Even though nucleation of polyethylene (PE) has been studied over the years, there was never a commercial introduction until Milliken's innovative team of chemical experts launched Hyperform HPN-20E. Our nucleating agent produces breakthrough performance, enhancing nearly every aspect of polyethylene, including optical and physical properties, processing, and barrier and seal properties.
Hyperform HPN-20E was launched in late 2006 as the first commercial nucleator for polyethylene. The initial focus was for blown film (primarily linear low-density polyethylene and high-density polyethylene), and successful trials have taken place all over the world. HPN-20E-nucleated polyethylene resins display the highest crystallization temperature and the lowest isothermal crystallization time achievable, and these features translate into a range of benefits.
More recent work has expanded its use in other applications, such as blow molding, rotational molding and injection molding.
