1.Material Composition: PET yog tsim los ntawm cov thermoplastic polymer, thaum PVC yog tsim los ntawm cov hluavtaws hluavtaws polymer. PET paub txog nws qhov meej, tawv, thiab ua haujlwm rau cov cua sov thiab tshuaj, thaum PVC paub txog nws qhov yooj yim, ua haujlwm ntev, thiab ua haujlwm tsis zoo.
2.Environmental Impact: PET raug suav tias yog ib puag ncig zoo dua li PVC vim tias nws tuaj yeem siv tau yooj yim dua thiab tsis muaj teeb meem rau ib puag ncig.

3.Application: PET films feem ntau yog siv rau ntim khoom noj, luam ntawv, thiab daim ntawv sau npe, thaum PVC films feem ntau yog siv rau shrink qhwv, rwb thaiv tsev, thiab hluav taws xob cable txheej daim ntaub ntawv.
4.Tus nqi: PVC feem ntau tsis tshua kim tshaj tus tsiaj vim nws cov nqi tsim khoom qis dua thiab muaj ntau dua.
Zuag qhia tag nrho, kev xaiv ntawm PET thiab PVC zaj duab xis nyob ntawm cov ntawv thov tshwj xeeb thiab cov kev xav tau. PET yog qhov kev xaiv zoo dua rau cov ntawv thov uas qhov pom tseeb thiab ua haujlwm rau cov cua sov thiab cov tshuaj yog qhov tseem ceeb, thaum PVC yog qhov kev xaiv zoo dua rau cov ntawv thov uas qhov yooj yim thiab kav ntev yog qhov tseem ceeb. Tsis tas li ntawd, kev txiav txim siab ib puag ncig kuj tseem tuaj yeem ua lub luag haujlwm hauv kev txiav txim siab.
