Fa'aaogāga
I le avea ai o se tasi ituaiga o le siosiomaga-faauo afi retardant, e mafai ona faʻaaogaina le afi tumau retarding suiga o polyester, ma le spinnability o le afi mumu polyester e tutusa ma PET, o lea e mafai ona faʻaaogaina i ituaiga uma o faiga vili, ma foliga e sili atu le vevela. mautu, leai se decompour i le taimi e milo ma leai se manogi.E mafai ona faʻaaogaina i vaega uma o talosaga a PET e faʻaleleia ai le gafatia antistatic o polyester.O le fua mo copolymerization o le PTA ma le EG o le 2.5 ~ 4.5%, o le phosphorus assay o le afi fa'alumaina pepa polyester o le 0.35-0.60%, ma le LOI o le afi mumu oloa e 30 ~ 36%.
