MILLIKEN & Company have launched Hyperform® HPN 210 M, a new, game-changing nucleating agent for injection moulded high-density polyethylene (HDPE) applications.
This technology features a unique crystalline orientation that improves the mechanical performance of HDPE to levels approaching those of PP impact copolymers. The Hyperform HPN 210 M nucleator gives moulders attractive new processing options for packaging and material handling applications. The new additive – which specifically targets material handling applications such as waste containers, totes, crates and pallets – is the first in a family of next-generation nucleators that Milliken is developing.
“Nucleating injection moulded PE has been an ongoing challenge throughout the industry that we’ve now addressed,” said Reed Walker, business development and marketing manager for Polyethylene Additives at Milliken. “With our new Hyperform HPN 210 M nucleating agent we are enabling injection moulders to expand the performance space of HDPE and linear low-density polyethylene.”
Milliken’s Hyperform HPN 210 M nucleator further improves the processing benefits of HDPE, including higher productivity due to shorter cooling times. The new nucleator’s unique ability to create lamellar crystal orientation of PE in the polymer flow (or machine) direction aids the reduction in shrinkage. Control of shrinkage and warpage contributes to an improvement in the overall quality of large, complex parts, opening the window for PE to become a potential material of choice in moulds that traditionally run PP, without the need to re-tool.
