During high-temperature processing, long-term storage, and outdoor use, polymers are highly susceptible to thermal oxidation degradation caused by heat, oxygen, and light exposure. This leads to issues such as yellowing, reduced mechanical strength, surface defects, and a shortened service life, which severely impact product quality and market reputation. To address the problem of material oxidation and aging at its source, a primary antioxidant with broad compatibility, high stability, and outstanding functionality is essential. As a classic and highly effective hindered phenolic primary antioxidant for organic polymers, Antioxidant 245 has become the preferred anti-aging additive for a wide range of polymer materials—including styrene, engineering plastics, rubber, polyurethane, and PVC—thanks to its excellent processing stability, color protection, resistance to leaching, and unique additive functions. It comprehensively enhances material processing quality and extends the service life of finished products.

Outdoor light exposure, acidic and alkaline environments, and the effects of metal catalysis are the primary culprits behind the aging, loss of gloss, discoloration, cracking, and performance degradation of plastic and coating products. As the main cause of outdoor aging, prolonged exposure to ultraviolet (UV) radiation can significantly shorten a product’s service life and diminish its aesthetic appeal and quality. Amid the ongoing evolution and upgrading of additives for new materials, the JADEWIN UV 312 oxalylphenylenediamine series of UV absorbers—with their versatile applicability, stable weather resistance, and excellent compatibility—have become the preferred additives in the plastics and coatings industries for long-lasting anti-aging protection, color retention, and quality enhancement, comprehensively addressing the challenges of UV aging in various polymer materials.

As the European Union’s environmental regulations continue to tighten, UV329—a UV absorber once widely used in polymer materials, coatings, and inks—has been officially added to the EU’s SVHC (Substances of Very High Concern) list and is now completely banned. This policy change has left many export-oriented companies facing multiple challenges, including limited material options, non-compliance with product standards, difficulties in updating legacy formulations, and insufficient weather resistance in finished products. As a result, there is an urgent need for a replacement product that offers equivalent performance, compliance, safety, and broad compatibility.

In the polymer materials, optical products, and coatings industries, UV-induced yellowing, cracking, and performance degradation have long been major challenges. As a broad-spectrum benzophenone-based UV absorber, JADEWIN BP-2 offers highly efficient absorption across the entire 260 nm–400 nm spectrum, covering the core UV-B to UVA range. It precisely addresses material photoaging challenges, making it the preferred light-stabilizing additive for high-end products.
