Akukho mahluko phakathi kwePET kunye neAPET yeplastikhi. I-PET yipolyester, enegama lekhemikhali le-polyethylene terephthalate. I-PET inokwenziwa kunye neepolymers ezilungelelaniswe ngeendlela ezimbini eziphambili; i-amorphous okanye i-crystalline. Ngokuphantse yonke into onxibelelana nayo yi-amorphous ngaphandle kwento enye ebalulekileyo; iitreyi zokutya ezincinci ze microwave, ukuba zenziwe ngePET, zenziwe ngeC-PET (crystallized PET). Ngokusisiseko zonke ii-PET ezicacileyo kubandakanya i-Mylar kunye neebhotile zamanzi zenziwe nge-A-PET (amorphous PET) kwaye kwiimeko ezininzi, i "A" ishiyekile.

Isimboli yeMobius loop yokuphinda isetyenziswe kwakhona kwipolyester yiPET ngenombolo 1, ke abantu abaninzi babhekisa kwipolyester njengePET. Abanye bakhetha ukucaciswa ngakumbi, ngokubonisa ukuba ngaba ipholiyesta yicrystalline C-PET, amorphous APET, irisayikilisha i-RPET, okanye i-glycol modified PETG. Ezi ziiyantlukwano ezincinci, ezijolise ekunciphiseni ukuqhubekeka kwepolyester kwimveliso yokuphela ekujongwe kuyo, nokuba ngenaliti yokubumba, ukubumba ngefuthe, ityrofomorming, okanye ukukhupha kunye nokugqiba imisebenzi njengokucheba ukusweleka.

I-PETG iza nenqaku eliphezulu kakhulu kwaye kulula ukuba isikwe kune-APET isebenzisa izixhobo eziqhelekileyo zokusika. Kwangelo xesha, ikwathambile kwaye ukukrwela kulula kakhulu kune-APET. Abaguquli abangenazo izixhobo ezifanelekileyo zokufa ukusikwa kwe-APET bahlala besebenza ne-PETG ngenxa yokuba i-PETG ithambile kwaye ukukrwela kulula, ke kuhlala kufihliwe nge-poly (olu luhlu lucocekileyo lwe "Saran wrap"). Le masking kufuneka isuswe kwelinye icala ngexesha lokuprinta, kodwa ukugquma kuhlala kushiyeka kwelinye icala ngexesha lokusika ukufa ukuthintela ukukrwela. Kuthatha ixesha elininzi kwaye kungoko kubiza kakhulu ukususa isigqubuthelo se-poly, ngakumbi ukuba kuprintwa amaphepha amaninzi.

Uninzi lweendawo zokubonisa zentengiso zenziwe kwi-PETG, kuba zihlala zinobunzima obunzima kwaye kunzima ukufa. Esinye isizathu kukuba i-poly masking ishiywe ukukhusela umboniso ngexesha lokuphatha nokuthumela kunye nokususwa xa kuboniswa umboniso. Esi sesona sizathu siphambili sokuba abaqulunqi abaninzi bacacise ngokuzenzekelayo i-PETG kwimiboniso yentengiso ngaphandle kokuqonda ukuba ngaba i-APET okanye iPETG yeyona nto ifanelekileyo ekusetyenzisweni kokugqibela okanye ekusetyenzisweni kwayo (ukuprinta, ukusika ukusweleka, ukunamathela, njlnjl.). I-APET ngokubanzi iyafumaneka ukuya kuthi ga kwi-0.030 ″ ubukhulu, ngelixa i-PETG ihlala iqala nge-0.020 ″.

Kukho umahluko ocashileyo phakathi kwePETG kunye neAPET, kwaye ukuba awuzazi izibonelelo kwaye ubuyela umva kwindlela eyenziwe ngayo iPET, ukukhumbula igama kuyabhidisa, kodwa kukhuselekile ukuthi konke oku kungasentla kubhekisa kwipolyester kwaye, Ukusuka kwindawo yokujonga kwakhona izinto, zonke ziphathwa ngokufanayo.
