Extrusion International 6-2023

29 Extrusion International 6/2023 of the flexible lip conveniently via the line control sys - tem. Depending on the die design, autonomous adjust- ment of the dust bar, width adjustment and lip opening via adjustment of the lower die lip is also possible. In combination with the Reifenhäuser Coextrusion Adap- tor Pro, PAM can also control the profiling of the indi - vidual layers while the line is running. This is significant - ly faster than conventional control by hand or thermal expansion bolts automation and enables faster start-up of good production, higher output and improved over- all equipment efficiency (OEE). Once recipes have been set, they can be stored and recalled at the push of a but- ton – even by inexperienced line operators, which is a decisive advantage against the background of the on- going shortage of skilled workers. In addition, energy consumption is significantly reduced compared to an automatic thermal expansion bolt system, as the screw- drivers only need to be supplied with power during the adjustment process and not permanently. PAM is not only available for Reifenhäuser flat film lines, but also for third-party lines as an upgrade via Rei- fenhäuser Extrusion Systems. Reifenhäuser Blown Film (BF) presented its latest blown film line concepts in Friedrichshafen. With the EVO Fusion technology the company offers a solution to one of the biggest problems in the use of recyclate in film production: on the one hand, ever higher pro - portions of recycled plastic are demanded, on the other hand, recyclate qualities fluctuate greatly and high- quality material is too expensive for many applications to produce economically. Thanks to twin-screw technol- ogy in the extruder, EVO Fusion can reliably process pre- viously unusable, low-cost recyclates. This results in high- performance and, above all, profitable blown films for applications such as trash bags or mailing bags. A special feature of the EVO Fusion is direct extrusion, which elim- inates the need for energy- and cost-intensive regranu- lation of the starting material. This means that fluff (film snippets) as well as all types of production waste and PCR material can also be processed directly. Reifenhäuser Group www.reifenhauser.com Reifenhäuser showcased its broad competence network at Fakuma. Thanks to in-house production of all important core components, the customer receives perfectly coordinated extrusion systems New TPVs With Up To 40% Recycled Content Sarlink® thermoplastic vulcani- zates (TPVs) are the premier choice for automotive applications requir- ing superior elasticity and long-term performance, as a recyclable, light- weight alternative to EPDM rubber. This latest series, Sarlink ® RX 3100B, was developed to help automotive brands achieve sustainability tar- gets, by incorporating up to 40% post-industrial recyclate, depending on the hardness. These multi-pur- pose TPVs are suitable for injection molding, extrusion, overmolding and co-extrusion with polypropyl- ene or other thermoplastic elasto- mers (TPEs). For these high-durom- eter grades, applications include the backbone or carrier for extruded seals, like in glass run channels, or boots, bellows, and other under hood components. The two grades, an 84 Shore A and 94 Shore A, are based on the existing Sarlink® 3100 Series tech- nology, but contain 25% and 40% recycled content, respectively. The materials process and perform simi- larly to their virgin counterparts yet offer sustainability benefits such as reduced dependency on virgin petroleum-based plastic. Sarlink RX 3100B TPVs are pre-colored black and can still be recycled in process or at the end of the product’s life cycle. The use of PIR content versus Post-Consumer Recycled (PCR) con- tent derived from household waste, provides for a more controlled and consistent raw material stream that can be used in extrusion-grade TPVs without issue. Teknor Apex treats recycled feedstocks like prime raw materials, and they are subject to the same quality assurance testing and must meet relevant specifica - tions for use. Teknor Apex www.teknorapex.com TPV with 40% recycled content is a multi- purpose TPV containing high-quality Post-Industrial Recycled (PIR) content and processes and performs like its virgin counterpart
