SEM Analysis on a New Kind of Phosphate Flame Retardant
The microscope characters of flame-retardant PC/ABS by a new kind of phosphate flame retardant, bisphenol-a bis (dipenyl phosphate) (BDP), is carried out in this paper using Scanning Electron Microscope (SEM). The result shows that flame retardant and unflame retardant materials before combustion and after indicate that these lame retardant materials after combustion shape countless closed holes which form sprangly cellular coking char layer, which also make out that BDP play the condensation flame retardant role in PC/ABS resin.
