1. Intshayelelo
I-Polyethylene terephthalate (PET) yenye yezona zinto ziguquguqukayo nezisetyenziswa kakhulu kwi-thermoplastics ehlabathini. Njengemathiriyeli ephambili yeebhotile zesiselo, ukupakishwa kokutya, kunye neentsinga zokwenziwa, i-PET idibanisa iipropathi ezibalaseleyo zomzimba kunye nokuphinda kusetyenziswe. Eli nqaku livavanya iimpawu eziphambili ze-PET, iindlela zokulungisa, kunye neentlobo ezahlukeneyo zezicelo kuwo wonke amashishini.

- Ubuninzi: 1.38-1.40 g/cm³ (amorphous), 1.43 g/cm³ (crystalline)
Ukumelana nemichiza
- Ukuchasana okugqwesileyo kumanzi, i-alcohols, ioyile
- Ukuchasana okuphakathi kwi-acids / iziseko ezibuthathaka
- Ukunganyangeki kakuhle kwiialkali ezinamandla, ezinye izinyibilikisi
Inkangeleko yeNdalo
- IKhowudi yokurisayikilisha: #1
- Umngcipheko we-Hydrolysis: Ukwehla kumaqondo obushushu aphezulu/pH
- Ukurisayikilisheka kwakhona: Inokuphinda isetyenziselwe amaxesha angama-7-10 ngaphandle kwelahleko enkulu yepropathi
3. Iindlela zokuSebenza
| Indlela | Usetyenziso oluqhelekileyo | Iingqwalasela ezingundoqo |

| Thermoforming | Iitreyi zokutya | Ukomisa kwangaphambili kubalulekile (≤50 ppm ukufuma) |
4. Izicelo ezingundoqo
Ukupakishwa (73% yemfuno yehlabathi)
- Iibhotile zesiselo: 500 yeebhiliyoni zeeyunithi ngonyaka
- Izikhongozeli zokutya: Iitreyi eziphehlwa yiMicrowavable, iiclamshell zesaladi
- Amachiza: Iipakethi zeblister, iibhotile zamayeza
Umqhaphu (22%).
- I-Polyester Fiber: Impahla, i-upholstery
- Iimpahla zobuGcisa: Iibhanti zokuhlala, iibhanti zokuhambisa
- I-Nonwovens: I-Geotextiles, imidiya yokucoca
Usetyenziso olusakhulayo (5% kodwa luyakhula)
- Ushicilelo lwe-3D: Imicu yamandla aphezulu
- I-Electronics: Iifilimu ezikhuselayo, izixhobo ze-capacitor
- Amandla aVuselelwayo: Ii-backsheets zephaneli yelanga
5. Inkqubela phambili yokuzinza
IiTekhnoloji zokuRecycling

6. Ukuthelekisa kunye nePlastiki engenye
| Ipropati | I-PET | HDPE | PP | I-PLA |
|---|---|---|---|---|
| Ukucaca | Egqwesileyo | Opaque | Translucent | Kulungile |
| Ukusetyenziswa okuphezulu kweTemp | 70°C | 80°C | 100°C | 55°C |
| Umqobo weoksijini | Kulungile | Ubuhlwempu | Phakathi | Ubuhlwempu |
| Ireyithi yokurisayikilisha | 57% | 30% | 15% | <5% |
7. Umbono wekamva
I-PET iyaqhubeka nokulawula ukupakishwa kokusetyenziswa kanye ngelixa isanda kwizicelo ezihlala ixesha elide ngokusebenzisa:
- Itekhnoloji yesithintelo esomeleziweyo (iingubo zeSiO₂, i-multilayer)
- Iziseko ezingundoqo zokurisayikilisha (i-PET ehlaziywe ngamachiza)
- Uhlengahlengiso lokusebenza (i-nano-composites, izilungisi zempembelelo)
Ngolungelelwaniso lwayo olulodwa lokusebenza, ukuqhubekeka kunye nokusebenziseka kwakhona, i-PET ihlala ibalulekile kuqoqosho lweplastiki yehlabathi ngelixa iguqulela kwiimodeli zemveliso ezijikelezayo.
