Imyunyungugu ya polyester idahagije nubwoko bukoreshwa cyane mubushuhe bwa thermosetting, ubusanzwe ni umurongo wa polymer uhuza umurongo wa ester hamwe nububiko bubiri butuzuye buterwa no guhuza aside ya dicarboxylique idahagije hamwe na diol cyangwa acide dicarboxylic yuzuye hamwe na diol zuzuye. Mubisanzwe, reaction ya polyester ikorwa kuri 190-220 ℃ kugeza igihe agaciro ka aside iteganijwe (cyangwa viscosity) igeze. Nyuma ya polyester condensation reaction irangiye, umubare munini wa vinyl monomer wongeyeho mugihe gishyushye kugirango utegure amazi meza. Iki gisubizo cya polymer cyitwa polyester resin idahagije.
Imyunyungugu ya polyester idahagije yageze ku ntera nini mu nganda nyinshi, nko mu gukora umuyaga w’umuyaga na yachts muri siporo y’amazi. Iyi polymer yamye yibanze kumpinduramatwara nyayo mubikorwa byo kubaka ubwato, kuko ishobora gutanga imikorere myiza kandi ihinduka cyane mugukoresha.
Ibisigazwa bya polyester bidahagije nabyo bikoreshwa mubucuruzi bwimodoka bitewe nubushakashatsi bwazo butandukanye, uburemere bworoshye, igiciro gito cya sisitemu, nimbaraga nke za mashini.
Ibi bikoresho kandi bikoreshwa mu nyubako, cyane cyane mu gukora ibikoresho byo guteka, amashyiga, amabati yo hejuru, ibikoresho byo mu bwiherero, hamwe n’imiyoboro n’ibigega by’amazi.
Porogaramu ya polyester idahagije resin iratandukanye. Polyester isigara mubyukuri igereranya imwe muri absolute
ibice bikoreshwa mu nganda zitandukanye. Icy'ingenzi, kimwe n’ibishushanyo byavuzwe haruguru, ni:
* Gukomatanya ibikoresho
* Irangi
* Flat yamashanyarazi, imbaho zometseho imbaho
* Ikoti rya gel kubwato, ibinyabiziga nubwiherero
* Amabara ya paste, yuzuza, stucco, putties hamwe na ankorike ya chimique
* Kuzimya ibikoresho
* Quartz, marble na sima yubukorikori
