JADEWIN AO136 Antioxidant: High-Efficiency Anti-Yellowing Radical Scavenger for High-Temperature Processing

In the industrial production of polymer materials such as polypropylene (PP), high-temperature extrusion and high-shear processing conditions can easily trigger thermal oxidative degradation of the polymer, leading to problems such as yellowing, reduced mechanical properties, and cosmetic defects, which severely impact the quality of the finished product and its market competitiveness. Traditional antioxidants generally suffer from high dosage requirements, poor high-temperature resistance, limited anti-yellowing effectiveness, and low overall cost-effectiveness, making them ill-suited for the production demands of continuous high-temperature processing in large-scale equipment. JADEWIN AO136, a high-efficiency benzofuranone antioxidant, was developed to address these challenges. With its excellent free radical scavenging capacity, high activity at low loading levels, and exceptional synergistic effects, it has become the preferred additive for preventing oxidation and yellowing during high-temperature processing of polymer materials.

Core Mechanism: Precisely scavenging free radicals to block thermal oxidative degradation at its source

Antioxidant 136 is a high-performance benzofuranone-based carbon and alkyl radical scavenger. Unlike traditional antioxidants, it directly targets and captures various reactive free radicals generated during polymer processing, halting oxidative chain reactions at the initiation stage and effectively inhibiting high-temperature thermal oxidative degradation of polymers. It is particularly well-suited for high-temperature, low-oxygen, high-shear extrusion processing environments, providing comprehensive

protection for the stability of polymer molecular structures. It effectively addresses issues such as yellowing, discoloration, and embrittlement that occur during material processing, laying a solid foundation for the processing stability of polymer materials.

Product Advantages: Overcoming Traditional Limitations to Achieve Low-Consumption, High-Efficiency Antioxidation

Compared to conventional hindered phenol antioxidants and phosphite antioxidants on the market, Antioxidant 136 offers revolutionary performance advantages, perfectly meeting the demands of large-scale, high-quality production. First, it features low dosage, high antioxidant efficacy, and excellent cost-effectiveness; even in trace amounts, it delivers outstanding high-temperature antioxidant performance, effectively reducing additive costs while avoiding issues such as material property interference and precipitation contamination caused by high dosage levels. Second, it is suited for demanding high-temperature processing conditions and exhibits exceptional thermal stability. It does not easily decompose or lose effectiveness under continuous high-temperature operation in large-scale extrusion equipment, consistently and stably providing antioxidant and anti-yellowing protection. Third, it offers strong compatibility and outstanding synergistic effects, working exceptionally well in combination with the mainstream hindered phenolic antioxidant JADEWIN AN1010 and the phosphite antioxidant JADEWIN AN168. When used in combination, these three additives form a comprehensive “primary antioxidant + secondary antioxidant + free radical scavenger” multi-layered protection system, significantly enhancing material processing stability and long-term aging resistance, with a remarkable synergistic effect where 1+1+1 > 3.

Precise Application: Focused on High-Temperature PP Processing, Specifically Addressing Yellowing Issues in Finished Products

JADEWIN AO136 is specifically designed for polypropylene (PP) processing and serves as a highly efficient antioxidant additive tailored for large-scale PP extrusion processes. In industrial mass production, the continuous operation of large-scale extrusion equipment—characterized by high speeds, high temperatures, and heavy loads—easily leads to localized overheating of the PP melt and a surge in free radicals, resulting in quality defects such as yellowing, uneven color, and batch-to-batch color variations in finished products. The addition of JADEWIN AO136 precisely inhibits high-temperature oxidative yellowing of the PP melt, stabilizes color consistency, and significantly improves the appearance quality and yield rate of finished products. It is perfectly suited for the large-scale production of various high-temperature extruded products, including PP pipes, sheets, modified pellets, and extruded profiles.

Product Value: Empowering High-Quality Mass Production in the Polymer Industry

For plastic processing companies, JADEWIN AO136 is not merely an antioxidant additive; it is a core auxiliary material that optimizes production processes, reduces production costs, and enhances product competitiveness. Its low-dosage formulation reduces raw material costs and minimizes the risk of additive residue and leaching; its exceptional high-temperature compatibility enables automated continuous mass production, reducing equipment downtime and the frequency of process adjustments; and its outstanding anti-yellowing and anti-aging properties significantly enhance product appearance and service life, helping enterprises overcome industry pain points such as yellowing and performance degradation during high-temperature PP processing, and achieve efficient, stable, and high-quality mass production.

Whether for conventional PP modification or demanding high-temperature extrusion conditions in large-scale equipment, JADEWIN AO136—with its core advantages of high efficiency, stability, synergistic performance, and cost-effectiveness—has become an indispensable key additive in the antioxidant systems for polymer material processing, ensuring quality upgrades for all types of plastic products!
