Polyester ni icyiciro cyapolymersikubiyemoester itsinda rikoramuri buri gice gisubiramo urunigi rwabo.Nkumwiharikoibikoresho, bikunze kwerekeza ku bwoko bwitwapolyethylene terephthalate(PET).Polyester zirimo imiti isanzwe ibaho, nko muriibimeranaudukoko, kimwe na sintetike nkapolybutyrate.Polyester karemano hamwe na sintetike nkeya niibinyabuzima, ariko ibyinshi bya polytike ya sintetike ntabwo.Synthetic polyester ikoreshwa cyane mumyenda.
Polyester fibre rimwe na rimwe izunguruka hamwe na fibre naturel kugirango itange aumwendahamwe nibintu bivanze.Impamba-polyester ivanze irashobora gukomera, iminkanyari- kandi irwanya amarira, kandi igabanya kugabanuka.Fibre ya sintetikeukoresheje polyester bifite amazi menshi, umuyaga hamwe n’ibidukikije ugereranije na fibre ikomoka ku bimera.Ni bakeirwanya umurirokandi irashobora gushonga iyo ikongejwe.
Liquid kristaline polyester iri mubintu byambere byakoreshejwe mu ngandaAmashanyarazi ya kirisiti.Zikoreshwa muburyo bwa mashini no kurwanya ubushyuhe.Izi mico nazo zingenzi mubikorwa byazo nkikimenyetso gishobora gukururwa na moteri yindege.
Polyester iboneka muri kamere harimogukataIbigizeibihingwa, igizwe naomega hydroxy aciden'ibiyikomokaho, bihujwe binyuzeesterinkwano, gukora polyester polymers yubunini butamenyekana.Polyester nayo ikorwa nainzukimu bwokoAmashanyarazi, isohora aselofane-kimeze nka polyester itondekanya ingirabuzimafatizo zabo zo mu kuzimu zihesha izina "inzuki za polyester".
Ukurikije imiterere yimiti, polyester irashobora kuba athermoplastiquecyangwathermoset.Harihopolyesteryakijijwe no gukomera;icyakora, polyester ikunze kugaragara ni thermoplastique.[11]Itsinda rya OH ryakiriwe hamwe naIsocyanateimikorere ikora muri sisitemu 2 igizwe na coating ishobora guhitamo pigment.Polyester nka thermoplastique irashobora guhindura imiterere nyuma yo gukoresha ubushyuhe.Nubwo ishobora gutwikwa nubushyuhe bwinshi, polyester ikunda kugabanuka kure yumuriro no kwizimya iyo ikongejwe.Fibre ya polyester ifite hejurugushikamanaE-moduluskimwe no kwinjiza amazi make kandi ntarengwakugabanukaugereranije nizindi fibre yinganda.
Kongera ibice bya aromatic ya polyester byongera ibyaboubushyuhe bwikirahure, gushonga ubushyuhe,ubushyuhe bwumuriro, imiti ihamye, hamwe no guhangana na solvent.
Polyester irashobora kandiitumanaho oligomersnka diol ya polycaprolactone (PCL) na polyethylene adipate diol (PEA).Hanyuma zikoreshwa nkaprepolymers.
