① Il-PET huwa polyethylene terephthalate, poliester saturat kristallin, abjad ħalib jew isfar ċar, polimeru kristallin ħafna, wiċċ lixx u tleqq. Hija raża komuni fil-ħajja u tista 'tinqasam f'APET, RPET u PETG.
② PETG huwa tip wieħed ta 'PET, jismu polyethylene terephthalate -1, 4-cyclohexane dimethanol ester, huwa kopoliester trasparenti u amorfu, PETG kopolimeru użat komunement huwa 1, 4-cyclohexane dimethanol, u PET aktar minn 1, 4-cyclohexane dimethanol copolymer, meta mqabbel ma 'PCT aktar ethylene glycol kopolimeru, għalhekk, PETG huwa differenti ħafna minn PET u PCT.
