Kuwonekera:
PET ndi zinthu zowonekera, zomwe zimapangitsa kuti zikhale zoyenera kuyika mapulogalamu pomwe mawonekedwe ake ndi ofunikira.
Opepuka:
PET ndi chinthu chopepuka, chomwe chimakhala chothandiza pakuyika chifukwa chimathandizira kuchepetsa mtengo wamayendedwe komanso kugwiritsa ntchito mphamvu.
Mphamvu:
Ngakhale kuti ndi yopepuka, PET ndi yamphamvu komanso yolimba. Amapereka mphamvu yabwino yamakina, ndikupangitsa kuti ikhale yoyenera kunyamula zinthu zomwe zimafunikira chitetezo.
Kukaniza Chemical:
PET imagonjetsedwa ndi mankhwala ambiri, zomwe zimapangitsa kuti zikhale zoyenera kusunga zinthu zosiyanasiyana, kuphatikizapo zakudya ndi zakumwa.
Recyclability:
Chimodzi mwazinthu zodziwika bwino za PET ndikubwezeretsanso kwake. Ikhoza kubwezeretsedwanso kangapo, zomwe zimathandiza kuti chilengedwe chisamawonongeke.
Zolepheretsa:
PET ili ndi zotchinga zabwino zolimbana ndi mpweya, mpweya woipa, ndi chinyezi, zomwe zimapangitsa kuti zikhale zoyenera kuyika zinthu zomwe zimafunikira kutetezedwa kuzinthu izi.
Kusinthasintha:
PET imatha kukonzedwa pogwiritsa ntchito njira zosiyanasiyana monga kuumba jekeseni, kuwombera, ndi kutulutsa, kulola kupanga zinthu zambiri, kuphatikizapo mabotolo, zotengera, ndi mafilimu.
Kumveka:
PET imapereka kumveka bwino, ndikupangitsa kuti ikhale chisankho chokonda pakuyika zinthu komwe kumawoneka kofunikira, monga momwe zilili ndi mabotolo omveka bwino a zakumwa.
Zotsika mtengo:
PET ndi zinthu zotsika mtengo, zomwe ndizofunikira pakupanga zinthu zambiri komanso kupanga zazikulu.
Kulimbana ndi Kutentha:
PET ili ndi kukana kwabwino kwa kutentha, kuilola kuti ipirire kutentha komwe kumachitika panthawi yolongedza, mayendedwe, ndi posungira.
Zosasintha:
PET sichitapo kanthu ndi zinthu zambiri zazakudya ndi zakumwa, zomwe zimapangitsa kuti ikhale yotetezeka komanso yoyenera kuyikamo ntchito pamakampani azakudya ndi zakumwa.

Mitundu yosiyanasiyana ya PET
Polyethylene terephthalate (PET) ikhoza kukhalapo m'mitundu kapena mitundu yosiyanasiyana kutengera kapangidwe kake ka maselo ndi katundu. Mitundu iwiri ikuluikulu ya PET ndi amorphous PET (APET) ndi crystalline PET (CPET). Mtundu uliwonse uli ndi mawonekedwe ake komanso ntchito zake:
Amorphous PET (APET):
Transparency: APET ndi yowonekera komanso yomveka bwino, zomwe zimalola kuti zomwe zapakidwa ziziwoneka bwino.
Kusinthasintha: Imasinthasintha kwambiri poyerekeza ndi crystalline PET, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kupindika kapena kupanga.
Kukonza: APET imagwiritsidwa ntchito nthawi zambiri popangira thermoforming, pomwe kutentha kumagwiritsidwa ntchito kuumba zinthuzo kuti zikhale zowoneka bwino.
Ntchito: Nthawi zambiri amagwiritsidwa ntchito poyikamo thireyi, kuyika matuza, ndi zotengera zowoneka bwino.
Crystalline PET (CPET):
Kukhazikika: CPET ndi yolimba kwambiri ndipo ili ndi malo osungunuka kwambiri poyerekeza ndi amorphous PET.
Kulimbana ndi Kutentha: Imakhala ndi mphamvu yolimbana ndi kutentha kwambiri, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimaphatikizapo kutentha kwambiri, monga ma tray ovenable.
Kukonza: CPET imagwiritsidwa ntchito nthawi zambiri popanga jekeseni ndi njira zotulutsira chifukwa cha kuuma kwake.
Mapulogalamu: Amagwiritsidwa ntchito kwambiri pakuyika zomwe zimafuna kukana kutentha, monga ma tray otha kutenthetsa ndi ma microwave, zotengera zowotchera, ndi mabotolo ena akumwa.
PET Yobwezerezedwanso (RPET):
Kukhazikika: Recycled PET imachokera ku kubwezeretsanso kwa zinthu za PET zomwe zimagwiritsidwa ntchito pambuyo pa ogula.
Katundu: Ngakhale kuti katunduyo amatha kusiyanasiyana kutengera njira yobwezeretsanso, rPET imagwiritsidwa ntchito nthawi zambiri pazinthu zomwe kukhazikika ndikofunikira.
Mapulogalamu: Amagwiritsidwa ntchito popanga mabotolo a PET obwezerezedwanso, zotengera, ndi zida zina zonyamula.
PETG (Glycol-Modified PET):
Kumveka bwino: PETG imapereka kumveka kofanana ndi APET ndipo imagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe kuwonekera ndikofunikira.
Impact Resistance: Yasintha kukana kwamphamvu poyerekeza ndi PET wamba, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafunikira kulimba.
Mapulogalamu: Amagwiritsidwa ntchito popanga ma CD omveka bwino, zowonetsera, ndi zida zamankhwala.
Biodegradable PET:
Zogwirizana ndi Zachilengedwe: Mitundu ya PET iyi idapangidwa kuti iwonongeke pansi pamikhalidwe ina, ndikupereka njira ina yosamalira zachilengedwe.
Katundu: Biodegradable PET imasunga zina mwazofunikira za PET yachikhalidwe koma ndi phindu lowonjezera la kuchepa kwa chilengedwe.
Mapulogalamu: Amagwiritsidwa ntchito poyika mayankho osamalira zachilengedwe.
