3.1. Qhov zoo thiab qhov tsis zoo ntawm polypropylene
Qhov zoo:
Lub teeb thiab muaj zog
Dej thiab tshuaj resistant
Durable
Rov ua dua
Qhov tsis zoo:
Tsis hloov pauv li PU
tuaj yeem kim dua PU
Tsis zoo ntawm cov insulator li PU
3.2. Qhov zoo thiab qhov tsis zoo ntawm polyurethane
Qhov zoo:
Yooj yim heev
Zoo insulator
Durable
Resistant rau abrasion thiab tsim kua muag
Muaj peev xwm ua tiav rau hauv ntau hom ntawv
Qhov tsis zoo:
Tsis zoo li dej resistant li PP
Nws tuaj yeem raug nqi ntau dua li PP
Tsis yog recyclable li PP
Txhawm rau xaiv cov yas zoo rau txoj haujlwm, nws yog ib qho tseem ceeb kom paub qhov zoo thiab qhov tsis zoo ntawm PP thiab PE. Kev nkag siab qhov sib txawv ntawm ob hom yas no tuaj yeem pab koj txuag nyiaj, ua cov khoom zoo dua, thiab txo koj cov kev cuam tshuam ib puag ncig.
