trifenilfoszfátnak

Trifenilfoszfát, often abbreviated as TPP or TPP, is an organic chemical compound with the formula (C₆H₅)₃PO₄. It is an ester of phosphoric acid and phenol. This white crystalline solid is generally insoluble in water but soluble in many organic solvents. Its primary industrial application is as a flame retardant, particularly in plastics and textiles, to reduce their flammability. TPP works by forming a char layer on the surface of the material when exposed to heat, which insulates the underlying material and prevents combustion.

Beyond its flame-retardant properties, trifenilfoszfát has also been used as a plasticizer to increase the flexibility and durability of polymers. It can be found in various consumer products, including some adhesives, coatings, and polyurethane foams. However, due to environmental and health concerns, its use has been restricted in certain applications and regions. Studies have raised questions about its potential for bioaccumulation and its effects on aquatic organisms. As a result, the search for safer alternatives to TPP has been ongoing in the chemical industry.
