Extrusion International 5-2025

55 Extrusion International 5/2025 Sustainability Goals and New Materials at K 2025 P olyplastics Group will announce a new broad-based sustainabil- ity strategy at the upcoming K 2025 exhibition. The company is proud to unveil its latest advancements in the DURAFIDE® polyphenylene sul de (PPS) technology and will also launch new materials in the DURAST® ne powders lineup and deliver the latest update on its new TOPAS® cyclic ole- n copolymer (COC) plant in Leuna, Germany. Polyplastics will update its set of sustainability commitments while announcing new technologies that are aimed at reducing the compa- ny’s global environmental footprint and accelerating progress towards a cleaner and healthier world. The drive to a circular economy includes the establishment of two carbon emission reduction goals. By 2030, Polyplastics, as part of the Daicel group, plans to reduce greenhouse gas (GHG) emissions by 50% com - pared to 2018. The company also tar- gets a 30% reduction in its cradle-to- gate product carbon footprint (PCF) compared with 2018. As part of its sustainability strategy which includes DURACIRCLE® Sus- tainable Solutions, Polyplastics will unveil unique technologies includ - ing the development of bio-based p- hydroxybenzoic acid (PHBA), which is a key monomer for LAPEROS® liquid crystal polymer (LCP). The company is also focusing development work on AI-aided mechanical recycling technology, POM chemical recycling technologies, and PBT solvent-based recycling processes. In new material developments, Polyplastics is introducing DURAST® fine powders made from its high- performance DURAFIDE® PPS. These powders feature a unique spherical shape and a precisely controlled, narrow particle size distribution, making them ideal for advanced processing needs. The company is also extending the application of DURAFIDE® PPS to lithium-ion bat- tery components, and launching new DURAFIDE® PPS grades specifi- cally engineered for laser-weldable applications – offering enhanced performance and design flexibility for cutting-edge industries. Polyplastics’ strategic manufacturing investments include a new TOPAS® COC plant that is currently under con- struction in Leuna, Germany. The new 25,000-ton plant will help Polyplastics meet growing worldwide demand. The facility will free up capacity for production of TOPAS® grades used in primary pharmaceutical and general medical packaging at the Oberhausen, Germany plant. The demand for COC is rising in a broad range of applica- tions with increasing use in sustainable packaging solutions. Polyplastics Co., Ltd. www.polyplastics-global.com/en/ K 2025: Hall 7A, Stand B02 Together, they are developing a pro- cess solution that enables recycling and compounding in a single stepwith only one melting process. The cooperation focuses on: • Recycling and compounding in one step – Optimization of mechani- cal properties through the addition of additives, llers (e.g. talc, calcium car - bonate, glass bers), and stabilizers. • High-performance degassing – Ef- cient removal of volatile contami - nants, for example for food-grade ap- plications. • Production of high-quality regran - ulates – Particularly suitable for PO lms that must meet high quality and defect-free requirements. With this solution, regranulates can be precisely tailored to the speci c ap - plication while simultaneously reduc- ing production costs and improving the CO 2 footprint. Material preparation is carried out using NGR’s proven C:GRAN technol- ogy, consisting of a cutter-compactor and a single-screw extruder. The ma- terial is then further processed in a Leistritz twin-screw extruder. This downstream compounding process produces the highest quality recycled material. The collaboration between Leistritz and NGR is a strong example of how sharing expertise and technology can set new standards in plastics process- ing: innovative, sustainable, and ready for the regulatory requirements of the future. Test Plant in Feldkirchen, Austria A joint recycling and compound- ing system installed at the NGR Test Center in Feldkirchen an der Donau allows the ef ciency of the coopera - tion to be demonstrated at any time. The system is designed for approxi- mately 300 to 500 kg/h and is avail- able for customer trials.
