Tricresyl phosphate is widely used as a plasticizer in the manufacturing of plastics and resins, particularly in PVC products, to enhance flexibility and durability. It is also employed as a flame retardant in various industrial applications, including coatings, adhesives, and sealants, due to its ability to reduce flammability. In the aviation industry, it serves as an additive in hydraulic fluids and lubricants to improve performance and stability under high-pressure conditions. Additionally, it is utilized in the production of varnishes and lacquers to provide resistance to water and chemicals. However, its use is regulated in certain applications due to potential health and environmental concerns.
