Used as a stabilizer in polymers, particularly in polyolefins, to protect against degradation caused by heat and light. It helps maintain the physical properties and appearance of plastics during processing and long-term exposure to harsh environments. Commonly found in agricultural films, packaging materials, and outdoor applications where UV resistance and thermal stability are critical. Also employed in rubber products to prevent discoloration and aging. Its effectiveness in low concentrations makes it suitable for use in transparent and colored formulations.
