Ubuningi 1.125g/cm3;
Indawo Yokuncibilika 60~65°C;
Inkomba Yokubukeza 1.458-1.461;
Iphuzu Lokukhanya 270°C;
Incibilika emanzini, utshwala kanye nezinye izinto eziningi ezincibilikisayo eziphilayo;
Umfutho Ophansi Womusi;
I-Thermal Stable; Ayisebenzi ngamakhemikhali amaningi; Ayinawo ama-hydrolyzed; Ayiwohlokanga.
I-PEG enesisindo sama-molecule ahlukene inezinhlobo ezahlukene zesimo somzimba. Ukubukeka kuyashintsha ngesisindo sama-molecule kusukela kuketshezi olujiyile (Mn=200~700), oluqinile njenge-wax (Mn=1000~2000) kuya kuqinile njenge-wax eqinile (Mn=3000~20000).
Idatha Yobuchwepheshe
| SN | Into | Iyunithi | Ibanga 1 | Ibanga lesi-2 |
| 1 | Mn | g/mol ×104 | 0.9～1.0 | 1.0～1.2 |
| 2 | Inkomba Yokuhlakazeka | D | ≤ 1.2 | |
| 3 | Inani le-Hydroxyl | i-mol KOH/g | 0.24～0.20 | 0.21～0.17 |
| 4 | Inani le-asidi | mg KOH/g | ≤ 0.05 | |
| 5 | Okuqukethwe kwamanzi | % | ≤0.6 | |
| 6 | Isikhathi Sokugcina | unyaka | ≥ 1 | |
Amanothi
1) yonke imininingwane yobuchwepheshe eboniswe ngenhla iwukubhekisela kuwe.
2) imininingwane ehlukile iyamukelekile ukuze kuxoxwe ngayo kabanzi.
Ukuphatha
Ukuphatha kwenziwa endaweni enomoya omuhle. Gqoka imishini yokuzivikela efanele. Vimbela ukusabalala kothuli. Geza izandla nobuso kahle ngemva kokuphatha.
Izinyathelo zokuphepha zokuphatha ngokuphephile. Gwema ukuthintana nesikhumba namehlo. Gwema ukukhiqizwa kothuli nama-aerosol. Nikeza umoya ofanele wokukhipha uthuli ezindaweni lapho kwakheka khona uthuli.
Isitoreji
Gcina endaweni epholile. Gcina isitsha sivaliwe kahle endaweni eyomile futhi enomoya omuhle. Izinga lokushisa elinconywayo lokugcina liyi-2 - 8 °C
Ulwazi lokuhamba
Akukalawulwa njengento eyingozi.
