Ua ntej, qhov ceev ntawm pob tshab mos PET cov ntawv yas yog feem ntau nyob ib ncig ntawm 1.33g / cm³. Cov yam ntxwv no ua kom lawv tswj tau lub zog thaum lub teeb yuag, ua kom yooj yim ua thiab kev thauj mus los. Nrog rau cov pa oxygen permeability ntawm kwv yees li 4-4.5 cmmm/(m24h0.1mpa), PET cov ntawv nthuav tawm cov pa oxygen zoo, tiv thaiv cov khoom ntim los ntawm oxidation. Tsis tas li ntawd, lawv cov dej noo permeability tsawg, nyob ib ncig ntawm 3Gmm / (M * 24H), ntxiv dag zog rau lawv cov kev ua tau zoo raws li cov khoom ntim.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, pob tshab mos PET cov ntawv yas muaj lub zog tensile ntawm 53 MPa ob qho tib si longitudinally thiab tom qab, nrog kev tawg elongation txog li 250%. Qhov no ua kom ntseeg tau tias lawv tiv taus kev tawg nyob rau hauv sab nraud quab yuam thiab muaj kev cuam tshuam zoo heev thiab compression tsis kam. Tsis tas li ntawd, cov ntawv PET nthuav tawm qhov hloov pauv me me thaum ua kom sov, nrog rau ob qho tib si longitudinal thiab lateral hloov tsis pub tshaj 5%, txhais tau tias lawv tswj qhov ntev ruaj khov nyob rau hauv qhov kub thiab txias yam tsis muaj deformation.
Transparency yog lwm qhov tseem ceeb ntawm pob tshab mos PET cov ntawv yas. Nrog lub pob tshab feem ntau qis dua 3%, lawv nthuav tawm lub ntsej muag zoo nkauj, ua rau lawv zoo tagnrho rau cov ntawv thov kom pom tseeb, xws li cov ntxaij vab tshaus tiv thaiv rau cov khoom siv hluav taws xob thiab ntim khoom noj. Tsis tas li ntawd, cov nplooj ntawv PET muaj qhov ua tiav zoo, tsis muaj qhov tsis xws li cov ntsiab lus siv lead ua thiab cov kab ntws, ntxiv dag zog rau lawv qhov zoo nkauj thiab kev ua tau zoo.
Hais txog kev tu cev, nws ua raws li cov qauv hauv tebchaws xws li GB13113-91, tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis ua rau mob, ua kom lawv tsis txhob kis cov khoom ntim. Tsis tas li ntawd, lawv tuaj yeem raug gamma ray sterilization, ua rau lawv siv dav hauv cov teb uas xav tau cov qauv kev nyiam huv, xws li zaub mov, tshuaj, thiab khoom siv kho mob.
