Widely used as a high-performance antioxidant and ultraviolet (UV) stabilizer in polymers and organic materials. It effectively prevents degradation caused by heat, light, and oxygen, making it ideal for enhancing the durability of plastics, rubber, and coatings exposed to harsh environmental conditions. Commonly added to polyolefins, polyurethanes, and adhesives to extend service life and maintain mechanical and optical properties. Also found in automotive parts, outdoor films, and packaging materials where long-term stability is critical. Its molecular structure allows for strong free radical scavenging and UV absorption, providing dual protective action. Exhibits good compatibility with other additives and resists volatilization at high processing temperatures.
