New offering expands the options for advancing the plastics circular economy

Ghent, Belgium – Milliken & Company, a globally recognized leader in polymer additives and colorants, has launched DeltaFlow Viscosity Modifiers specifically to help polypropylene (PP) recyclers.

Recyclers can use DeltaFlow, a solid concentrate, to increase the melt flow rate of recycled polypropylene (rPP) for the extrusion and injection molding processes. Milliken offers DeltaFlow in free-flowing pellets, which makes the product easy to feed, safe to handle and dust free.

DeltaFlow-optimized resins allow for lower processing temperatures, which can enable converters to reduce cycle times, boost productivity and improve processability.

Brand owners stand to benefit, as well. DeltaFlow enables recycled polypropylene to feasibly replace virgin resin in many end-use applications. This allows brands to use more rPP in their products, thereby helping them to meet their sustainability goals.

This new concentrate nicely complements Milliken’s existing family of DeltaMax® Performance Modifiers for polypropylene that enhances the physical properties and melt flow of rPP resins by allowing recyclers and converters to optimize their formulations and blends machine-side.

“Milliken is pleased to be adding to its portfolio of products that assist polypropylene recyclers.” said Tugce Asici-van Houselt, Milliken’s sales manager for Plastic Additives in Europe/Middle East/Africa (EMEA).

Milliken, which currently produces the DeltaFlow products in Germany, offers them in concentrations of 2, 5 and 10 percent to meet varying applications and equipment requirements.

“Milliken & Company remains committed to supporting the plastics recycling industry with advanced polymer additives that allow for the increased use of recycled content by improving the properties of the recycled PP resin itself. DeltaFlow Viscosity Modifiers are just the latest example of this effort, which in turn, contributes to the industry’s ongoing push to promote sustainability,” adds Asici-van Houselt.
