Used in polymer manufacturing to prevent oxidative degradation during processing and extended use. Enhances the durability of plastics exposed to high temperatures and UV radiation. Commonly added to polyolefins, rubber, and adhesives to maintain mechanical properties and color stability. Also employed in industrial lubricants and greases to extend service life by inhibiting oxidation of base oils. Effective in combination with other stabilizers for synergistic protection in coatings and elastomers.
