Phosphate ester fire resistant fluid has excellent anti-wear and fire resistance properties.

Phosphate ester fire resistant fluid is primarily used as a fire-resistant basestock in applications such as hydraulic systems, turbines and compressors.

Phosphate esters were formerly a common derivative of coal tar and as a result consisted of a mixture of isomeric aryl phosphates, including the neurotoxic orthotolyl phosphate.

However this production method has declined along with the commercial use of coal tar. Today, phosphate esters are commonly derived from the reaction of phosphorus oxychloride
