Description

Triphenyl Phosphate (CAS NO 115-86-6) is a versatile organophosphate compound widely used as a flame retardant and plasticizer. Its primary value lies in its ability to enhance fire safety and improve the physical properties of polymer materials without significantly compromising their performance. This chemical is essential for manufacturers in the plastics, electronics, and construction industries seeking reliable, high-performance additives for their formulations.

Application

• As a flame retardant plasticizer for engineering plastics like polycarbonate, polyphenylene oxide (PPO), and PVC.
• As a viscosity modifier and friction reducer in advanced hydraulic fluids and lubricants.
• As an additive and intermediate in the synthesis of other organophosphorus compounds.
• In the production of fire-resistant coatings and films for textiles and electronic components.
• As a non-flammable plasticizer for cellulose acetate and nitrocellulose in specialty applications.
• In the formulation of certain adhesives and sealants requiring improved flame retardancy.
