Polyethylene yog cov yooj yim tshaj plaws polymer, yog cov ntaub ntawv ntau tshaj plaws siv polymer.
Nws yog los ntawm rov ntsuas dua qhov -CH2-unit. Polyethylene yog tsim los ntawm kev ntxiv polymerization ntawm ethylene (CH2 = CH2) .Polyethylene odorless, non-toxic, xav zoo li wax, nrog rau kev kub tsis zoo (yam tsawg kawg kub txog -70 ~ -100 ℃), stability tshuaj zoo, feem ntau ntawm cov kua qaub (acid and base oxidative) ntawm cov kua qaub (acid), nyob rau hauv chav tsev sov tsis yog soluble hauv kev hnyav, dej haus, hluav taws xob rwb thaiv tsev, tab sis polyethylene yog qhov yooj yim heev rau tej chaw ntxhov siab (tshuaj thiab khoom siv), thiab muaj tsis kub kub laus tiv thaiv.
