ABSTRACT

Since the discovery of their excellent antiwear and fire-resistance properties in the 1940s, the use of phosphate esters by the lubricants industry has steadily increased. As a result of many years of research and practical experience,

industry has learnt to manufacture and formulate these versatile chemicals to satisfy a wide variety of demanding applications. Although the basic composition of products currently in commercial use has remained unchanged for over 30 yr, new applications continue to be found and the products are, today, regarded as cost-effective lubricant additives and safe, non-hazardous, hydraulic fluids and lubricants.
