Tri-p-cresyl phosphate is widely used as a plasticizer in the manufacturing of plastics and synthetic resins. It enhances the flexibility, durability, and flame resistance of materials such as PVC, making it valuable in the production of cables, wires, and flooring. Additionally, it serves as a flame retardant in various industrial applications, including coatings and adhesives, where fire safety is critical. In hydraulic fluids and lubricants, it acts as an anti-wear additive, improving performance and extending the life of machinery. Its use in aviation hydraulic systems is notable due to its stability under high temperatures and pressures. However, careful handling is required due to potential toxic effects.
