Cov tais CPET, lossis Crystalline Polyethylene Terephthalate cov tais, yog ib hom ntim khoom noj ua los ntawm ib hom khoom siv thermoplastic. CPET paub txog nws qhov kev tiv taus zoo heev rau qhov kub thiab txias siab thiab qis, ua rau nws yog qhov kev xaiv nrov rau ntau yam kev siv ntim khoom noj.

A Yog, cov tais yas CPET siv tau rau hauv qhov cub. Lawv tuaj yeem tiv taus qhov kub thiab txias txij li -40°C txog 220°C (-40°F txog 428°F), uas tso cai rau lawv siv rau hauv qhov cub microwave, qhov cub ib txwm muaj, thiab txawm tias khaws cia rau hauv khov.

A Qhov sib txawv tseem ceeb ntawm CPET cov tais thiab PP (Polypropylene) cov tais yog lawv qhov tiv taus cua sov thiab cov khoom siv. CPET cov tais tiv taus cua sov ntau dua thiab tuaj yeem siv rau hauv ob qho tib si microwave thiab cov qhov cub ib txwm muaj, thaum PP cov tais feem ntau yog siv rau kev siv microwave lossis khaws cia txias. CPET muaj kev ruaj khov zoo dua thiab tiv taus kev tawg, thaum PP cov tais muaj kev ywj pheej ntau dua thiab qee zaum tuaj yeem pheej yig dua.

Cov tais CPET yog siv rau ntau yam kev siv ntim khoom noj, suav nrog cov pluas noj npaj txhij, cov khoom ci, cov khoom noj khov, thiab lwm yam khoom uas yuav lwj uas xav tau rov ua kom sov lossis ua noj hauv qhov cub lossis lub tshuab hluav taws xob microwave.

CPET thiab PET yog ob hom polyesters, tab sis lawv muaj cov khoom sib txawv vim lawv cov qauv molecular. CPET yog ib daim ntawv crystalline ntawm PET, uas ua rau nws muaj zog dua thiab tiv taus qhov kub siab thiab qis dua. PET feem ntau yog siv rau cov fwj dej haus, cov thawv ntim khoom noj, thiab lwm yam kev siv ntim khoom uas tsis xav tau tib qib kev kam rau qhov kub thiab txias. PET yog pob tshab dua, thaum CPET feem ntau yog opaque lossis semi-pob tshab.
