data,” said Schmutz. “Through ELiSANA, I look forward to strengthening engagement across the value chain and helping to ensure that essential substances like antioxidants and light stabilisers remain available for safe and sustainable use. A col- laborative approach is vital to securing a strong, future-ready European industry built on the best available science.”

in automotive, agricultural film, and synthetic turf. Most recently, the company introduced two new systems designed for greenhouse films: Sabostab UV 728 and Sabostab UV 980. Both systems are combinations of newly introduced N-Alkoxy HALS, with outstanding chemical resistance, with a highly film-persistent triazine UV absorber. Sabostab UV 728 is formulated to meet most requirements for use in greenhouse films with high exposure to agrochemicals, and Sabostab UV 980 is intended for specifically high-risk applications, where agrochemical use is very intense, the company said. Another area of focus is automotive. UV stabilis- ers in automotive thermoplastic materials provide durability and improves the lifecycle assessment (LCA) profile of plastic products. Environmental footprint is becoming increasingly important for new compound formulation, the company said.
Additive safety Songwon is committed to advancing industry-wide collaboration, shaping regulatory policies, and promoting data-driven regulatory guidance within the chemical sector, the company announced, as evidenced in the recent appointment of Thomas Schmutz, Leader Technology, Regulatory Affairs & Sustainability at Songwon, as the new chair of the European Light Stabiliser and Antioxidant Associa- tion (ELiSANA), a non-profit sector group of the European Chemical Industry Council (Cefic). “As regulatory requirements grow in complexity,
strong scientific cooperation is more important than ever. Many decisions made in Europe are quickly mirrored globally, so it is critical to support policymakers with sound science and reliable

Additive Technical Committee (ATC), the Global Organotin Stewardship Council (GOSC), the Light Stabiliser and Antioxidant Consortia (LiSAO), the OrganoTin Consortium (OTR), and the European Council for Alkylphenols and Derivatives (CEPAD). “These efforts are becoming increasingly critical as regulations shift toward full life-cycle responsibility and demand greater transparency from chemical producers,” the company said. Songwon recently announced that it had expand-
ed its partnership with Biesterfeld Spezialchemie; the company is now the exclusive distributor for Song- won’s range of polymer stabilisers in the markets of Romania, Bulgaria, Croatia, Montenegro, Bosnia & Herzegovina, Kosovo and North Macedonia.
New PA stabiliser BYK developed a new UV stabilising system for polyamides exposed to UV radiation, particularly for outdoor applications, including furniture as well as automotive interior and exterior parts. BYK-MAX LS 4128 is an organic system supplied as a granulated, free-flowing concentrate with a high level of active ingredient in an ethylene copolymer carrier. The system is a combination of HALS stabilisers with other radical-scavenging components, including peroxide decomposers and additional antioxidants. “This formulation enhances the overall stabilisa- tion performance by addressing multiple degrada- tion pathways – particularly those involving UV- induced radical formation and peroxide buildup,” the company said. “HALS neutralize UV-induced radicals, peroxide decomposers prevent chain scission, and antioxidants protect against heat during processing and long-term use. Together with BYK’s proprietary surface chemistry and radical-scavenging technologies, this synergy ensures high material durability,” the company explained. The new system is an addition to the company’s other modified concentrates for stabilisation of polyolefins and polyamides. Clariant announced that it is expanding produc- tion in China through its joint venture with Beijing Tiangang Auxiliary Co, which commissioned a second production line at its Cangzhou facility in China. The new line will primarily manufacture
