Polyester ni icyiciro cyapolimabirimoester itsinda ry'imikoreremuri buri gice gisubiramo cy'uruhererekane rwabo rw'ingenzi. Nk'ikintu cyihariyeibikoresho, akenshi yerekeza ku bwoko bwitwapolyethylene tereftalate(PET). Polyester irimo imiti isanzwe, nko muriibimeranaudukoko, kimwe n'ibintu by'ubukorikori nkapolybutyratePolyester karemano n'izindi nke zikozwe mu buryo bwa sintetike niibora, ariko polyester nyinshi zo mu bwoko bwa sintetike si zo. Polyester zo mu bwoko bwa sintetike zikoreshwa cyane mu myenda.
Hari igihe imigozi ya polyester ivangwa hamwe n'imigozi karemano kugira ngo hakorweumwendahamwe n'imiterere ivanze.Ipamba-Uruvange rwa polyester rushobora gukomera, rudacika iminkanyari cyangwa ngo rucike, kandi rugabanya kugabanuka.Indodo z'ubukorikoriGukoresha polyester bifite ubushobozi bwo kurwanya amazi menshi, umuyaga n'ibidukikije ugereranije n'imigozi ikomoka ku bimera. Biba bikebirwanya umurirokandi ishobora gushonga iyo ishyushye.
Polyester zikozwe mu buryo bwa crystalline ziri mu za mbere zakoreshejwe mu ngandapolymeri za kristu y'amaziZikoreshwa kubera imiterere yazo ya mekanike no kwirinda ubushyuhe. Izi miterere ni ingenzi mu ikoreshwa ryazo nk'agapfukamunwa gashobora kwirindwa muri moteri z'indege.
Polyester iboneka mu bidukikije irimocutinigice cyaibimera byo mu kanwa, igizwe naaside omega hydroxyn'ibikomoka kuri byo, bihujwe binyuzeesterimigozi, ikora polimeri za polyester zifite ingano idasobanutse. Polyester nazo zikorwa nainzukimu bwoko bwaAmakoleti, bitangacellophane-nk'ururabo rwa polyester ku turemangingo twabo tw'abana bo munsi y'ubutaka bibahesha izina ry'akabyiniriro "inzuki za polyester".
Bitewe n'imiterere y'ibinyabutabire, polyester ishobora kubathermoplasticcyangwathermosetiHariho kandiresins za polyesterbyavuwe n'ibikoresho byo gukomera; icyakora, polyester zikunze gukoreshwa cyane ni thermoplastics.[11]Itsinda rya OH ryasubijwemoIsocyanateikora neza mu buryo bubiri butanga irangi rishobora guhindurwamo irangi. Polyester nka thermoplastics zishobora guhindura imiterere nyuma yo gukoresha ubushyuhe. Nubwo zishobora gushya mu bushyuhe bwinshi, polyester zikunda kugabanuka ku muriro no kwizima iyo zitangiye gushya. Fibre za polyester zifite uburebure bwakwihangananaE-moduluskimwe no kubura amazi menshi no kugabanyakugabanukaugereranije n'izindi nganda zikora imigozi.
Kongera ibice bihumura neza bya polyester byongeraubushyuhe bw'impinduka mu kirahure, ubushyuhe bushonga,guhagarara neza k'ubushyuhe, kudahindagurika kw'imiti, no kudahangana n'ibintu bishongesha.
Polyester na yo ishobora kubaikoranabuhanga oligomernka polycaprolactone diol (PCL) na polyethylene adipate diol (PEA). Hanyuma bikoreshwa nkaprepolymers.
