PETG robobin PET ne da aka gyara. Filastik ne mai haske, copolyester ba crystalline, PETG da aka saba amfani da shi comomer shine 1,4-cyclohexanedimethanol (CHDM), cikakken suna shine polyethylene terephthalate-1,4-cyclohexanedimethanol. Idan aka kwatanta da PET, akwai ƙarin 1,4-cyclohexanedimethanol comonomers, kuma idan aka kwatanta da PCT, akwai ƙarin ethylene glycol comonomers. Saboda haka, aikin PETG ya bambanta da na PET da PCT. Samfuran sa suna da fa'ida sosai kuma suna da kyakkyawan juriya na tasiri, musamman dacewa da samar da samfuran gaskiya masu kauri.

A matsayin kayan tattarawa,PETyana da fa'idodi masu zuwa:
1. Yana da kyawawan kayan aikin injiniya, ƙarfin tasiri shine sau 3 ~ 5 na sauran fina-finai, juriya mai kyau, kuma har yanzu yana da kyau a -30 ° C;
2. Mai jure wa mai, mai, dilute acid, dilute alkali, da mafi yawan kaushi;
