Description

2,5-Bis(tert-Dodecyldithio)-1,3,4-Thiadiazole is a high-performance sulfur-based organic compound primarily utilized as an extreme pressure (EP) additive and anti-wear agent. This compound matters because it provides exceptional load-carrying capacity and thermal stability, significantly enhancing the performance and longevity of lubricants and greases under severe operating conditions. Industrial buyers in the lubricant formulation, metalworking, and automotive additive sectors rely on this chemical to develop advanced products that reduce friction, prevent scuffing, and protect critical machinery components.

Application

• As a key extreme pressure (EP) additive in industrial gear oils, transmission fluids, and metalworking fluids.
• As an anti-wear agent in engine oils, hydraulic fluids, and compressor oils to reduce surface fatigue.
• In the formulation of high-performance greases for automotive, mining, and steel mill applications.
• As a multifunctional additive providing both EP and antioxidant properties in synthetic and semi-synthetic lubricants.
• In traction fluids and other specialty lubricants requiring high thermal and oxidative stability.
• As a friction modifier in fuel-efficient lubricants to improve energy economy.
