Polyethylene feem ntau muab faib ua ib qho ntawm ntau lub tebchaw loj, feem ntau muaj xws li LDPE, LLDPE, HDPE, thiab Ultrahigh Molecular Nyhav Polypropylene. Lwm yam txawv xws li Medium Density Polyethylene (MDPE), Ultra-low-molecular-weight polyethylene (ULMWPE lossis PE-WAX), High-molecular-weight polyethylene (HMWPE), High-density cross-linked polyethylene (HDXLPE), Hla-txuas polyethylene (PEX lossis XLPE), Polyethylene tsawg-density (VLDPE), thiab Chlorinated polyethylene (CPE).
Low-Density Polyethylene (LDPE) yog cov khoom siv tau yooj yim heev nrog cov khoom ntws tshwj xeeb uas ua rau nws tsim tshwj xeeb rau cov hnab yuav khoom thiab lwm yam ntaub ntawv yas zaj duab xis. LDPE muaj ductility siab tab sis tsis tshua muaj zog tensile, uas yog tshwm sim nyob rau hauv lub ntiaj teb no tiag tiag los ntawm nws propensity mus stretch thaum strained.
Linear Low-Density Polyethylene (LLDPE) zoo ib yam li LDPE, tab sis muaj qhov zoo ntxiv. Tshwj xeeb, cov khoom ntawm LLDPE tuaj yeem hloov kho los ntawm kev hloov kho cov qauv tsim, thiab tag nrho cov txheej txheem tsim khoom rau LLDPE feem ntau tsis tshua muaj zog dua li LDPE.
High-Density Polyethylene (HDPE) yog ib qho muaj zog, muaj zog ntawm cov yas nrog lub siab polyethylene-hdpe-trashcan-1 crystalline qauv. Nws feem ntau yog siv rau hauv cov yas rau cov thawv ntim mis, cov ntxhua khaub ncaws ntxhua khaub ncaws, cov khib nyiab khib nyiab, thiab cov ntawv txiav.
Ultraigh molecular hnyav polyethylene (UHMW) yog qhov hnyav tshaj plaws ntawm polyethylene feem ntau ib qho kev txiav txim ntawm qhov ntau dua li HDPE. Nws tuaj yeem raug spun rau hauv cov xov nrog lub zog tensile ntau zaus ntau dua li cov hlau thiab feem ntau muab tso rau hauv cov tsho tiv thaiv mos txwv thiab lwm yam khoom siv ua haujlwm siab.
