SI Group, a leading global developer and manufacturer of performance additives, process solutions, pharmaceuticals, and chemical intermediates, will showcase its portfolio of innovative additive technologies at K 2025.

SI Group will showcase its portfolio of innovative additive technologies at K 2025.
At its booth, the company will highlight its latest solutions that enhance performance and sustainability across a variety of plastics applications. Technical experts will present their latest solutions in recycled polypropylene, PFAS-free additives, and Arvin-free technologies designed for automotive, packaging, and consumer applications.
Featured products at SI Group’s booth include:
WESTONTM 705: A next-generation, nonylphenol-free liquid phosphite antioxidant for plastics and elastomers. Approved for food contact in more than 50 countries, it is a best-in-class stabilizer for polyethylene blown films.
LOWINOXTM 1790: High-performance hindered phenolic antioxidant designed to be more effective at preventing spandex oxidation and degradation than commonly used HN-150/LOWINOX GP45 blend. With an enhanced safety and environmental profile, LOWINOX 1790 does not generate NDMA or any known carcinogens.
LOWINOXTM TBM6: Hindered thiophenol antioxidant that is highly pure and clean, specifically designed for high voltage cable insulation.
NAUGARD BIO-XLTM: An accelerator with over 95% biocarbon-based content for sulfur curing of natural and synthetic rubbers. NAUGARD BIO-XL does not release harmful nitrosamines as listed in TRGS552.
NAUGATACTM 1068-ULM: SI Group’s latest tackifier offers a reduced SVHC-content option, enhances tack retention in a wide range of elastomers, including tire compounds, treads, hoses, belts, and other rubber articles, and delivers performance equal to or better than conventional tackifiers.
These products will be showcased through an interactive booth display designed to demonstrate their technical benefits and applications.
“Our presence at K 2025 underscores our commitment to advancing circular and responsible solutions. We remain focused on meeting regulatory requirements while ensuring our additive platforms, like EVERCYCLE and NAUGARD BIO-XL, continue to deliver the reliable, high-performance results our customers expect,” said Robert Kaiser, VP Polymer Solutions and Managing Director at SI Group.
