Key Applications of 6,6-Di-tert-butyl-p-cresol:

Antioxidant in Lubricants:It is used in the formulation of automotive lubricants and engine oils to prevent oxidative degradation. By inhibiting oxidation, it helps maintain the performance and longevity of lubricants, ensuring they do not break down prematurely in high-temperature environments.
Rubber and Plastics:DTBPC is often added to rubber and plastic products to prevent oxidative damage and extend the lifespan of products exposed to oxygen, heat, and light. It helps in stabilizing the material and preventing hardening or brittleness.
Fuel Additives:In the fuel industry, 6,6-di-tert-butyl-p-cresol is used to prevent the oxidation of fuels, especially in gasoline and diesel, thereby ensuring that the fuels maintain their stability and performance over time.
Polymer Stabilization:It is used in the production of polymers, particularly polyethylene and polypropylene, to improve their resistance to oxidation, UV degradation, and thermal degradation.
Plastics and Synthetic Materials:This antioxidant is added to synthetic polymers (like polymethyl methacrylate and polycarbonate) and plastics to enhance their durability and resistance to aging.
