4,4'-Oxydiphthalic anhydride (ODPA) ose vailaʻau vaʻaia vaʻaia e iai le tele o faʻaoga i le gaosiga o oloa eseese. ODPA cas 1823-59-2 o se pa'epa'e tioata pa'epa'e e fa'apipi'iina e ala i le tali i le va o le phthalic anhydride ma phenols.
4,4'-Oxydiphthalic anhydride cas 1823-59-2 ose vaega autu i le gaosiga o polymers maualuga e pei o polyimides, polyesters, ma resins epoxy. O nei polymers e sili ona lelei masini, vevela, ma vailaʻau, e faʻaaogaina ai i le tele o faʻaoga e pei o le aerospace, mea tau eletise, ma fale taʻavale.
O Polyimides o polymers e fa'asaoina i le vevela o lo'o fa'aaogaina i talosaga e mana'omia ai mea fa'ainisinia lelei. O nisi faʻataʻitaʻiga o nei faʻaoga e aofia ai bearings, gears, ma faʻamaufaʻailoga. 4,4'-Oxydiphthalic anhydride cas 1823-59-2 o se mea taua tele faʻaaogaina i le gaosiga o polyimides e pei ole PMDA-ODA, BPDA-ODA, ma le BPDA-PDA.
Epoxy resins e faʻaaogaina e fai ma faʻapipiʻi, faʻapipiʻi, ma tuʻufaʻatasia i pisinisi eseese.ODPA cas 1823-59-2e faʻaaogaina i le gaosiga o resini epoxy e pei ole bisphenol A-ituaiga epoxy resins ma novolac-ituaiga epoxy resins. O nei resini o loʻo i ai le pipii lelei, malosi maualuga, ma le faʻamaʻiina o vailaʻau e talafeagai mo le faʻaaogaina i le fausiaina, gataifale, ma fale eletise.
O polyesters o se isi ituaiga polymer e mafai ona gaosia e faʻaaoga ai le ODPA e avea o se vaeluaga. O nei polymers e maualuga le malosi, tumau, ma fetuutuunai, e faʻaaogaina mo le tele o faʻaoga e pei o filo ie, mea faʻapipiʻi, ma paʻu.
O le ODPA o loʻo faʻaaogaina foi i le gaosiga o mea faʻapipiʻi e pei ole ortho-phthalate esters. O nei palasitika ua faʻaopoopoina i polymers e faʻateleina ai lo latou fetuutuunai ma le tumau. O palasitika fa'avae ODPA e sili ona lelei le fa'atinoga o le vevela ma fa'aaogaina i fa'aoga e fa'atatau ai le fetu'una'i.
I le faaopoopo atu i lona faʻaaogaina i le gaosiga o polymers ma plasticizers,4,4'-Oxydiphthalic anhydride cas 1823-59-2e fa'aaogaina e pei o se afi mumu i le gaosiga o oloa eletise ma eletise. E mafai foi ona faʻaaogaina e fai ma sui faʻafesoʻotaʻi i le gaosiga o mea faʻapipiʻi, faʻapipiʻi, ma isi oloa.
I le faaiuga,4,4'-Oxydiphthalic anhydride cas 1823-59-2ose vaila'au va'ava'ai va'ava'ai e tele fa'aoga taua i alamanuia eseese. O lona faʻaogaina i le gaosiga o polymers maualuga, palasitika, faʻamaʻi afi, ma isi oloa ua saofagā i le alualu i luma o le tele o tekinolosi. Ona o ona uiga fa'apitoa ma fa'aoga eseese, o le ODPA ose vaila'au taua tele e ono fa'aauau pea ona faia se sao taua i le lumana'i atina'e o pisinisi eseese.
