Cov cuab yeej no ua rau nws tsim nyog rau kev siv hauv kev lag luam xws li tshuaj, khoom noj khoom haus thiab dej haus, thiab kev ua tshuaj lom neeg, qhov twg raug rau ntau yam tshuaj. PET cov tshuaj tiv thaiv ua kom cov khoom ruaj khov, kev nyab xeeb, thiab kev ntseeg tau.

-Thermal Stability: Polyethylene terephthalate pom zoo thermal stability, cia nws tiv taus ntau qhov kub thiab txias yam tsis muaj kev puas tsuaj loj. Nws muaj qhov siab melting point, uas ua rau nws siv tau rau hauv cov ntawv thov uas yuav tsum tau ua kom sov thiab thermal stability. PET feem ntau ua haujlwm hauv kev lag luam hluav taws xob thiab hluav taws xob rau cov khoom xws li cov khoom sib txuas, cov khoom siv hluav taws xob, thiab cov rooj sib tham.

-Barrier Properties: Lwm cov cuab yeej tseem ceeb ntawm PET yog nws cov khoom thaiv zoo heev tiv thaiv cov pa roj, noo noo, thiab aroma. PET zaj duab xis thiab cov thawv ntim khoom ua haujlwm zoo, tiv thaiv cov khoom ntawm cov pa oxygen, dej vapor, thiab cov ntxhiab tsw sab nraud. Cov cuab yeej no ua rau nws zoo tagnrho rau cov ntawv ntim khoom, tshwj xeeb hauv kev lag luam zaub mov thiab dej haus, uas nws pab txuas ntxiv lub neej txee ntawm cov khoom thiab tswj lawv cov tshiab.

-Recyclability: PET yog cov khoom siv rov ua dua tshiab, ua rau nws muaj kev ruaj ntseg ib puag ncig. Nws tuaj yeem siv rau hauv ntau yam khoom, suav nrog lub raj mis PET tshiab, polyester fibers rau textiles, thiab txawm tias cov khoom ntim tsis yog khoom noj. Kev rov ua dua tshiab ntawm PET tau ua rau muaj kev siv ntau ntxiv thiab cov phiaj xwm tsom rau kev txo cov khib nyiab thiab txhawb kev lag luam ncig.
