Polyethylene glycol yog cov ntaub sa cov saw hlau tsim los ntawm cov pab pawg ethylene oxes oxide, nrog ib pab pawg hydroxyl ntawm txhua qhov kawg, ua rau nws cov tshuaj polymerized. Raws li cov txheeb ze lub cev hnyav nce ntxiv, polyethylene glycol maj hloov kua rau ib lub waxy tawv, thiab nws hygroscopicity txo qis; Cov tshuaj lom tsawg dua raws li qhov kev txheeb ze hnyav nce ntxiv. Polyethylene glycol nrog ib tug txheeb ze molecular ceeb thawj ntawm ntau tshaj 4000 yog nruab nrab, tsis muaj tshuaj lom, thiab muaj zoo biocompatibility. Nws muaj kev nyab xeeb rau tib neeg lub cev, tab sis tseem rhiab rau qhov kub.
Polyethylene Glycol 6000 yog daim ntawv dawb waxy tawv lossis cov hmoov av uas tsis muaj tshuaj lom thiab nplaim taws retardant. Nws tau thauj raws li ib qho tshuaj ntsuam xyuas dav dav, ntim thiab khaws cia rau hauv qhov chaw qhuav. Nws muaj cov khoom siv muaj zog, ua yeeb yaj kiab ua yeeb yaj kiab, thiab muaj peev xwm txhim kho kev siv yeeb tshuaj ntawm cov ntsiav tshuaj. Nws feem ntau yog siv los ua cov thaiv hluav taws xob hauv txheej teving thiab dav siv ua cov nplaum hauv cov ntsiav tshuaj hauv cov tshuaj. Nws tuaj yeem ua rau cov ntsiav tshuaj ci iab thiab du, thiab tsis yooj yim lossis puas. Nws kuj tseem tuaj yeem hloov kho rau viscosity los ntawm kev ntxiv cov kua polyethylene glycol thiab siv ua ib qho kev vam meej matrix. Piv nrog lipophilic matrices, nws muaj ntau yam zoo. Piv txwv, cov ntsiab lus txhawb cov ntsiab lus me me tuaj yeem npaj tau, uas tuaj yeem tiv thaiv cov teebmeem ntawm huab cua siab; Daim tso tawm cov tshuaj tsis raug cuam tshuam los ntawm melting point; Nyob rau lub sijhawm cia, lub cev ruaj khov yog qhov zoo.
