Extrusion International 5-2023-USA

48 Extrusion International 5/2023 FAKUMA 2023 Certified Recyclates for High-Quality Applications At Fakuma 2023, WIS Kunstst - offe will present its capabilities as a compounder and distributor. WIS Kunststoffe places particular em- phasis on its high-quality regranu- lates. WIS offers recyclates from both post-consumer sources (PCR) and post-industrial sources (PIR). Daniel Römhild, authorized signato - ry at WIS Kunststoffe, explains, "We have secured long-term access to recycling streams and, because we have our own production facilities, we can respond very individually to our customers' requirements. In our fully equipped in-house laboratory, we can constantly monitor the qual- ity of our products at the highest level." WIS Kunststoffe offers com - pounds with different recycled con- tent optimized for specific applica - tions. For example, recyclates with high color purity can be offered in white or natural colors, which have approval for the production of cos- metic packaging or toys. At Fakuma, WIS Kunststoffe will show odor-optimized polypropyl- ene and polyethylene recyclates. These are suitable for sensitive ap- plications, such as toys or house - hold applications. For applications in the automotive industry, spe - cial "high-tech" recyclates (PCR) have been developed that meet the high standards of the industry and already fulfill the criteria of the upcoming regulations in this area. Reinforced variants are also offered for exterior components, while odor-optimized grades with low emission values are available for interiors. Also new are polyam- ides with high heat resistance for technical applications, especially in the engine compartment. For the packaging industry, WIS now offers recycled polystyrenes (rPS). All materials fromWIS Kunststoffe have application-specific approv - als. These include European food approvals according to (EU) No. 10/2011 , FDA, leave-on & rinse-off for cosmetics (EC) No. 1223/2009 and EN-71 for the toy industry. All com- mon conformities can be confirmed, such as REACH, California Proposi - tion 65, SVHC, etc. Furthermore, automotive applications can be real- ized according to European as well as global standards. Individual solu- tions for applications from the elec- tronics sector (some with flame re - tardancy) can also be implemented, always tailored to the requirements of the respective project. New Schneckenputzer – Maximum cleaning at a low price WIS now also offers its cus- tomers unique cleaning gran- ules from its own production. The granules are marketed un- der the name "Schneckenputzer" (screw cleaner). Conveyor screws and hot runners can be complete- ly cleaned in a short time by us- ing Schneckeputzer. "The special feature of our screw cleaner is the cost-effective and fast cleaning be- tween material changes and that parts can optionally be produced with it, so that the tool can remain on the machine at all times and the production process is thus hardly interrupted" explains Daniel Röm - hild. "This brings considerable ad - vantages. The operator does not have to supervise the entire clean- ing procedure; rather, it is enough to fill in the screw cleaner, set the machine and let it run. After a few cycles, the machine, the screw and, if necessary, the hot runner are cleaned and ready for use again. The number of cycles depends, of course, on the degree and type of contamination and the polymer used." For longer machine down - times, the cleaners can be used as a freezing mixture so that carbon deposits cannot emerge.
