High-Efficiency Water-Based Antioxidant 245DW: The Core Guardian of Polymer Material Quality

2025/12/10

During the processing and long-term use of polymer materials, thermal oxidative degradation poses a significant challenge threatening product quality and service life, potentially leading to issues such as yellowing, brittleness, and diminished mechanical properties. We introduce the high-performance water-based antioxidant 245DW, featuring 40% antioxidant 245 as its core active ingredient uniformly dispersed in water. This product delivers exceptional antioxidant efficacy and broad compatibility.


As an organic polymer primary antioxidant, 245DW belongs to the category of high-performance hindered phenolic antioxidants. Its core advantage lies in efficiently interrupting the chain reaction of thermal oxidative degradation in polymer materials during processing and use. Unlike traditional antioxidants, its water-dispersible formulation not only meets environmental requirements for aqueous processing but also delivers three core characteristics: low volatility, outstanding color stability, and anti-extraction properties. Low volatility prevents additive loss and environmental pollution caused by high temperatures during processing. exceptional color stability ensures consistent appearance in light-colored and vibrant products, while extraction resistance guarantees sustained antioxidant efficacy even after prolonged use or exposure to media, continuously safeguarding product quality.


The product boasts extensive application scenarios, comprehensively covering multiple polymer material sectors. It precisely adapts to styrene, synthetic rubbers (such as styrene-butadiene rubber—widely used in elastic materials for tires and conveyor belts), polyoxymethylene (POM) homopolymers and copolymers, polyurethane (PU), polyamide (PA), polyester (PET), methyl methacrylate (MBS), and polyvinyl chloride (PVC). Addressing specific processing challenges across materials, 245DW delivers tailored solutions: during PVC and ABS processing, it functions as an efficient chain terminator to regulate polymerization reactions and enhance processing stability; in flexible PVC products, it effectively reduces white spot defects, optimizing product appearance and tactile feel.


Regarding synergistic applications, 245DW demonstrates excellent compatibility and synergistic effects. To address UV-induced aging in outdoor products, it can be combined with benzotriazole UV absorbers and hindered amine light stabilizers to form a dual-protection system against thermal oxidation and photo-oxidation, significantly extending product lifespan. Furthermore, when combined with thioester auxiliary antioxidants, it produces a pronounced synergistic effect. Through the synergistic mechanism of “primary antioxidants eliminating free radicals + auxiliary antioxidants decomposing hydrogen peroxides,” it achieves an antioxidant effect where “1+1>2,” delivering superior stability and protection at lower dosage levels.


Whether enhancing processing efficiency, optimizing product quality, or extending product lifespan, water-based antioxidant 245DW delivers efficient and reliable antioxidant solutions for the polymer industry through its exceptional performance, broad compatibility, and flexible synergistic advantages. It empowers enterprises to achieve high-quality production and product upgrades.
