FR and mechanical properties while improving processability in highly filled wire and cable compounds. In wire and cable extrusion, the additive mitigates melt fracture and reduces die drool and torque during extrusion, enabling customers to run their lines at higher throughput, minimise downtime for die cleaning, and produce higher-quality cables, the company reported. Evonik launched its first PFAS-free PPA alterna- tive solutions, Tegomer 6810 and Tegomer 6850, in 2023 and has continued to work in this area. The company said it now offers three 100% active materials and several corresponding dilutions for easier handling in LDPE, LLDPE, and PP in the Tego PPA and Accurel PPA ranges. “Based on our technical analysis, we have identified organomodified siloxanes (OMS) as the next best alternatives to fluorine-based PPAs,” said Miriam Schehr, Head of the Global Applied Technology and Technical Service Department for Plastics Additives at Evonik. “Our portfolio now includes an OMS-based PFAS-free PPA with broad food-contact compliance for packaging, film, and fiber applications, as well as a siloxane-free PPA. Dilutions in common polymers allow customers to

integrate these products easily into masterbatches or conversion processes.” Evonik noted that the additives do not
migrate, which enables use in applications such as some multilayer film structures and in metallised barrier films. Ingenia Polymers continues to develop
new products in its line of non-PFAS PPAs, aiming to further improve time to clear melt fracture and prevention of die buildup. “We are seeing continued growth in adoption of Ingenia’s non-PFAS PPA offerings in the blown film, cast film, BOPP/BOPE, extrusion coating and laminating, blow moulding and pipe extrusion markets across
