industry and provide a range of other processing, energy reduc- tion and system cost benefits. The net effect is that converters, brand owners and OEMs can now meet market needs for higher impact driven by e-commerce shipments and increasing automotive safety standards, while keeping a keen eye on improving sustainability and costs. DeltaFlow viscosity modifiers for
rPP are based on the latest viscosity-modification chemistry and are solid concentrates designed to specifically help PP recyclers by increasing the melt flow rate of rPP for injection moulding processes. This reduces energy use and enhances circularity. The technology also has lower volatile organic compounds (VOCs) and improved organoleptics and complement advances being made in recy- cling machinery. DeltaFlow-optimised resins allow for lower processing temperatures, which can enable converters to reduce processing tempera- tures, reduce energy use, boost productivity and improve processability.
The company adds that Hyperform HPN additives provide faster, easier and more finely tuned PP resin perfor- mance and enhance injection- moulded rPP resins. The additives
resolve production issues that converters can encounter with
traditional nucleators, such as shrinkage, warpage and the trade- off between stiffness and impact performance. It also enables energy
savings and increases productivity. Milliken recently partnered with Erema and
PreZero to highlight the use of Hyperform HPN performance additives in rPP compounds. “Using post-consumer waste collected by PreZero, the company leveraged its formulation expertise using Erema recycling technology and Milliken’s additive to make recycled PP resins,” says Vivian Luk, Global Product Line Manager Plastic Additives Hyperform HPN. “Milliken’s performance additive upgrades the rPP by improving the material’s physical properties while also reducing the cycle time needed to process it. These additives also provide for better
