GHENT – DeltaFlow viscosity modifiers are being launched by Milliken & Company specifically to help polypropylene (PP) recyclers.
A solid concentrate, it can be used to increase the melt flow rate of recycled PP (rPP) for the extrusion and injection moulding processes. It is supplied in free-flowing pellets, which makes the product easy to feed, safe to handle and dust free.
DeltaFlow-optimised 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, because DeltaFlow enables recycled PP to feasibly replace virgin resin in many end-use applications. This allows brands to use more rPP in their products, helping them to meet their sustainability goals.
The new concentrate complements Milliken’s existing family of DeltaMax performance modifiers for PP that enhance the physical properties and melt flow of rPP resins by allowing recyclers and converters to optimise their formulations and blends machine-side.
Milliken currently produces the DeltaFlow products in Germany in concentrations of two, five and 10% 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,” said Tugce Asici-van Houselt, Milliken EMEA sales manager for plastic additives. “DeltaFlow viscosity modifiers are just the latest example of this effort, which in turn, contributes to the industry’s ongoing push to promote sustainability.”
