Right: Syensqo introduced a portfolio of busbar


solutions at K2025


In a collaboration with Brazilian health technol- ogy companies Hanisch Medical and TechImport, the guides give surgeons with a lighter, more radiotransparent alternative to traditional metal instruments. They are up to 70% lighter than traditional metal versions while maintaining strength and durability, and are compatible with all major sterilisation methods, including steam, ethylene oxide and gamma radiation. The breakthrough is in the material’s radiotrans-


parency. Unlike metal, the polymer does not interfere with intraoperative imaging such as X-rays, which gives benefits such as: greater precision; optimised efficiency; and enhanced ergonomics. The company also introduced a portfolio of busbar solutions at K2025. For extruded busbars, used in battery systems, it has developed Ryton PPS XE3500 Orange grade, for higher reliability and compliance in high-voltage environments. For more complex geometries and demanding electrical environments, such as inverters and e-motors, it provides high-CTI injection-moulded materials. Products like Amodel PPA Bios, Amodel PPA HFFR and Ryton Supreme HV have achieved the latest UL Prospector Surface Tracking Test (STT) certification, with Amodel Bios HFFR exceeding requirements up to 900V and Ryton Supreme HV achieving 650V. “As the automotive industry accelerates towards electrification, our customers need more than just materials – they need a partner they can trust at every stage of development,” said Nicolas Batailley, automotive marketing manager at Syensqo. The company has also developed a proprietary chemical recycling technology to obtain purified raw material monomers from sulfone polymers (PSU, PPSU and PESU). The technology builds on Syensqo’s Echo sulfone polymers portfolio and uses chemical recycling to break down formulated polyarylether- sulfone (PAES) content in post-industrial produc- tion scrap (PIR) and post-consumer parts (PCR) into monomer feedstock for reuse in new polymer products. The purified monomers can be incorpo- rated into Udel PSU, Radel PPSU or Veradel PESU as well as other thermoplastics or even epoxy resin formulations without loss of performance. “Our circular PAES technology is a step forward for customers seeking to advance their sustainabil- ity goals,” said Floryan De Campo, vice president of life solutions at Syensqo Specialty Polymers. “By enabling the recycling of sulfone polymers, we help reduce carbon footprint and increase recycled

Sustainable relays


Siemens has launched a series of coupling relays that have housings made from a plastic that is 70% bio-based. The material, Akulon K225-KS B-MB plastic was developed by Envalior and is derived from biomass waste – specifically used cooking oil (UCO) from sources including the food industry. Because UCO is no longer suitable for human or animal consumption, it does not compete with food or animal feed production, says Envalior. And while UCO is mainly used for biodiesel, Envalior uses it to make engineering plastics based on a mass balance concept. “Collaborating with Envalior to create this bio-based plastic is an important step towards advancing the use of more sustainable materials in our electrical products,” sais Andreas Matthé, CEO of electrical products at Siemens Smart Infrastructure. The company’s Sirius 3RQ4 coupling relay comes in three variants for a range of industrial requirements. The product can be easily disman- tled and recycled at the end of its life. Akulon K225-KS B-MB, a bio-based, halogen-


free, flame-retardant polyamide 6 for injection moulding, has an improved environmental profile, high heat- and chemical- resistance and is used in electrical engineering and power distribution applications. Marc Rudolf, global key account manager at


Envalior, added: “A key success factor in this project was achieving excellent flow behaviour in thin-wall designs and a UL94 V-0 rating at 0.4 mm thickness – while simultaneously achieving an
