Used primarily as an additive in lubricants and oils to enhance their performance under extreme conditions. It acts as an antioxidant and anti-wear agent, extending the life of machinery by reducing friction and preventing degradation of the lubricant. Commonly applied in automotive and industrial settings where high temperatures and pressures are prevalent. Also utilized in the formulation of greases and metalworking fluids to improve stability and efficiency. Its role in reducing oxidation and wear makes it valuable in maintaining the integrity of mechanical systems over time.
