Polyethylene feem ntau yog muab faib ua ib qho ntawm ntau cov khoom sib xyaw tseem ceeb, feem ntau suav nrog LDPE, LLDPE, HDPE, thiab Ultrahigh Molecular Weight Polypropylene. Lwm cov variants suav nrog Medium Density Polyethylene (MDPE), Ultra-low-molecular-weight polyethylene (ULMWPE lossis PE-WAX), High-molecular-weight polyethylene (HMWPE), High-density cross-linked polyethylene (HDXLPE), Cross-linked polyethylene (PEX lossis XLPE), Very-low-density polyethylene (VLDPE), thiab Chlorinated polyethylene (CPE).
Polyethylene Uas Tsis Ntev (LDPE) yog ib yam khoom siv uas yooj ywm heev nrog cov yam ntxwv ntws tshwj xeeb uas ua rau nws tsim nyog rau cov hnab yuav khoom thiab lwm yam yas yas. LDPE muaj qhov ductility siab tab sis lub zog tensile qis, uas pom tseeb hauv lub ntiaj teb tiag tiag los ntawm nws qhov kev nyiam ncab thaum raug nias.
Polyethylene Linear Low-Density (LLDPE) zoo ib yam li LDPE, tab sis muaj ntau yam zoo dua. Tshwj xeeb, cov yam ntxwv ntawm LLDPE tuaj yeem hloov pauv los ntawm kev kho cov khoom sib xyaw, thiab cov txheej txheem tsim khoom rau LLDPE feem ntau siv zog tsawg dua li LDPE.
Polyethylene Siab (HDPE) yog ib hom yas uas ruaj khov, nruab nrab tawv nrog cov qauv crystalline polyethylene-hdpe-trashcan-1. Nws feem ntau siv rau hauv cov yas rau cov thawv mis nyuj, cov tshuaj ntxhua khaub ncaws, cov thoob khib nyiab, thiab cov laug txiav.
Ultrahigh Molecular Weight Polyethylene (UHMW) yog ib hom polyethylene uas muaj qhov ntom ntom heev, feem ntau nws qhov hnyav molecular loj dua HDPE. Nws tuaj yeem raug ntswj ua xov nrog lub zog tensile ntau zaus dua li hlau thiab feem ntau siv rau hauv cov tsho tiv thaiv mos txwv thiab lwm yam khoom siv ua haujlwm siab.
