Extrusion International 6-2024-USA

36 Extrusion International 6/2024 FAKUMA 2024 Optimised Sliding and Abrasion Behaviour without PFAS L ubmer UHMW-PE grades from Mitsui Chemicals of- fer high-performance solutions where applications for engineering plastics place increased demands on sliding, abrasion and wear behaviour. In many cases, these materials, which are suitable for both injection moulding and extrusion, can replace the previous stan- dard solution PTFE, which will no longer be produced in Europe in the future, if its high heat resistance is not re- quired. In addition to their excellent tribological proper- ties, they are characterised by good chemical resistance, low density, very low water absorption and high flexi - bility and impact strength at low temperatures. Another advantage is the low noise development during sliding movements. Dreyplas, Meerbusch, is the distributor for Lubmer materials in the DACH region. The Lubmer granulate range includes the highly abra- sion-resistant types L3000, L4000 and L5000, which differ in terms of their molecular weight. In addition, the special Real-Time Measurements in the Polymer Melt – No Sampling and No Waiting Time C olVisTec from Berlin, the world's leading special- ist for inline process monitoring in the extrusion of polymers, exhibited its InSpectro series at Fakuma. This is a proven spectroscopic technology used internation- ally in compounding and recycling in three variations: UV/Vis, NIR and Raman. In addition to the classic real-time 24/7 process monitoring in extrusion, ColVisTec exhibited two im- portant tools, specially developed together with SKZ, Würzburg, for the use in mechanical recycling (post con- sumer and industrial). The first is automated color control to a predefined target color value with RecyColor. Regardless of the fluctuations in the input material, a predetermined col - or value is maintained reliably and constantly by control- ling the dosing unit for the pigment addition (Picture 1). As a second tool, ColVisTec offers the new product RecyQuant based on near-infrared spectroscopy, which enables the determination of the contaminant polymer content in the polymer melt during operation (Picture 2). Furthermore, the residual moisture can also be de- tected and quantified directly. ColVisTec AG www.colvistec.de
