Hauv qhov teeb meem thib ob, peb tseem qhia cov yam ntxwv ntawm cov khoom siv raw EVA, yog li txhua tus tuaj yeem pom meej meej tias peb cov khoom tseem muaj txiaj ntsig zoo.
7. Nplaim-retardant: EVA muaj nplaim-retardant tom qab hloov mis.
8. Kev tiv thaiv xeb: tsis muaj xeb rau cov khoom siv hlau.
9. Tsis muaj kuab paug: Cov khoom no tsis muaj tshuaj lom, tsis qab, tsis muaj kab mob, noj kab, thiab tsis rot.
10. Zoo nkauj tsos: du thiab tiaj tus, muaj yeeb yuj thiab ntau yam.
11. Kev tsim kho yooj yim: Cov khoom siv tau yooj yim rau txheej txheem thiab tuaj yeem txiav raws li qhov xav tau. Thaum hloov kho cov cuab yeej, cov khoom siv rwb thaiv tsev tuaj yeem siv tau ntau zaus los txo tus nqi rwb thaiv tsev.
12. Cov txheej txheem: Tsis muaj pob qij txha, thiab yooj yim rau txheej txheem xws li kub nias, txiav, gluing, thiab tsevneeg.
13. Kev tiv thaiv kev vibration: muaj zog tiv taus thiab nruj nruj, muaj zog tawv, thiab muaj kev poob siab zoo/tiv thaiv kev ua haujlwm.
EVA muaj ntau tus yam ntxwv, haum rau ntau daim ntawv thov, thiab siv tau ntau yam tuaj yeem tsim kho. Yuav tsum muaj kev xav tsis thoob. Peb ntseeg tias siv EVA los ua raw khoom rau peb cov khoom yog qhov raug tshaj plaws.
