| 22.04.2024 Plastics Insights 3/2024 (p. 56-59) Testing Recyclates Directly during Injection Molding and Extrusion NIR Process for the Inline Inspection of Recyled Plastics Contaminants in recyclates can cause damage to injection molding machines and extruders. And they can also give rise to flaws in the manufactured products. This can be avoided by checking the quality of the recyclates directly during processing. A method adopted from the field of colorimetry for use in the NIR range is ideal for this purpose. (read more)

22.08.2022 Kunststoffe international 6/2022 (p. 39-43) Luminous Markers instead of Holy Grail Improved Sorting of Plastic Waste with Luminescent Pigments The HolyGrail 2.0 Initiative aims to improve the sorting of plastic waste. Fur this purpose, digital watermarks containing information on packaging type, material, and usage will be applied on products. However, the method also has certain drawbacks. Here, luminescent pigments provide an alternative that is permanent and can withstand several processing cycles.

26.07.2022 Kunststoffe international 5/2022 (p. 50-51) The Color Loop Ensuring Color Consistency of Recycled Materials The mass of recyclable plastic waste has been growing steadily for years. This is mainly the result of technical advances made in both processing and sorting. At the same time, the recycling targets set by the EU are piling more and more pressure on companies to increase the amount of recycled plastics in their products. This in turn is raising the requirements imposed on the recycled materials themselves. Aside from the nature of the polymer and the previous application, the color of the recycled material is important.
