with certified circular polymers using its Exxtend technology for advanced (chemical) recycling of plastic waste. It says these certified circular poly- mers can deliver the same performance as virgin resins which is critical if the value chain wants to use recycled content for sensitive applications like food grade packaging. Among other solutions, ExxonMobil will show mono-material designs, such as PE/PE laminates, which are designed for recyclability by reducing the number of components, including those often considered more difficult to recycle. �

HPF The Mineral Enginee- rs, a division of Quarzwerke, will present its latest development in mineral additives for odour manage- ment in recycled compounds at K2022. The company says that, with
sustainability becoming increasingly
important, the use of high-quality plastic recyclates in new products is demanded wherever possible. However, contaminated post-consumer or post-in- dustrial plastic waste represents a major challenge as the required level of quality often cannot be achieved. The odour profile of recyclates, in particular, often causes dissatisfaction, with impurities or the recycling process itself causing unpleasant odours. HPF has formulated a range of mineral-based odour absorbers. Olfatometric tests have shown that, when blended into a post-consumer PP recyclate at a level of 5% in a twin-screw extruder, the resulting compounds presented an odour intensity significantly below the threshold set in the VDA 270 automotive standard. �

Milliken says it is putting its new measures to advance the circular economy through chemistry front and centre stage at K2022. As well as its additive product portfolio, it is also highlighting its 30 partners including its ongoing partnership with PureCycle Technologies, whose patented technol- ogy turns recycled PP into virgin-like material. Milliken’s DeltaMax performance modifiers for recycled PP can balance melt flow, impact strength, and stiffness to increase overall performance for recycled materials. DeltaMax also helps converters reduce energy by running machines with faster cycle times or lower temperatures. DeltaFlow Viscosity Modifiers are solid concen-
trates designed to specifi- cally help PP recyclers by
increasing the melt flow rate of
recycled PP for extrusion and injection moulding processes.
