Chlorinated organophosphate esters

WebMar 28, 2024 · Organophosphate ester flame retardants consist of straight (alkyl) or aromatic (aryl) chains attached to a phosphate moiety. Some OPFRs, e.g., Tris (1-chloro-2-propyl) phosphate (TCPP), are also chlorinated. OPFRs are mainly used as flame retardant plasticizers in engineering plastics ( Brandsma et al., 2013 ).
