Application

4,4-Thiobis(6-tert-butyl-m-cresol), often referred to as Antioxidant 300, serves a vital role in the rubber and plastics industries as a highly effective, non-polluting phenolic antioxidant. Characterized by its white to light gray powder form and aromatic odor, this compound is primarily employed to inhibit radical formation and prevent thermal decomposition, thereby safeguarding materials from oxidation and deterioration. It offers excellent thermal stability and weather resistance, with the added benefit of minimal impact on the electrical properties of end products. Compatible with materials such as polypropylene, ABS, polystyrene, and others, it is especially suitable for creating white, bright-colored, and transparent products. Moreover, its low volatility, low toxicity, and solubility in various organic solvents make it a versatile choice, even in applications involving food-contact plastics across numerous countries. Additionally, it enhances performance when used alongside carbon black and octadecyl alcohol.
