Used primarily as an antioxidant in polymers and plastics, this compound helps prevent degradation caused by heat, light, and oxygen exposure during processing and long-term use. It is especially effective in polyolefins such as polyethylene and polypropylene, enhancing the material’s stability and extending product lifespan. Common applications include packaging films, automotive parts, and household containers where thermal and UV resistance are critical. It is also used in adhesives, sealants, and lubricants to maintain performance under high-temperature conditions. Due to its ester composition, it offers good compatibility with hydrophobic matrices and low volatility at elevated temperatures.
