A comparative study of the fire-retardant efficiency of three commercial ar
yl phosphates-triphenyl phosphate (TPP), resorcinol bis(diphenyl phosphate)
(RDP) and bisphenol A bis(diphenyl phosphate) (BDP)-in PC/ABS blends was c
arried out. The thermal and hydrolytic stability of the fire-retardant resi
ns, as well as their physical properties, was also studied. The use of RDP
and BDP is preferred over TPP because of superior properties, whereas BDP s
hows better fire-retardant efficiency, hydrolytic stability, and thermal st
ability than RDP.
