Polyethylene Glycol
Kiato 1.125g/cm3;
Te Pūwāhi Rewa 60~65°C;
Taupū Whakaata 1.458-1.461;
Pūwāhi Ngaro 270°C;
Ka wairewa i roto i te wai, te waipiro me te maha atu o ngā whakarewa waro;
Pēhanga Kohu Iti;
Pūmau ki te wera; Kāore e tauhohe ki ngā matū maha; Kāore e hauwai; Kāore e pirau.
He rerekē ngā momo āhua ā-tinana o te PEG me te taumaha ngota rerekē. Ka rerekē te āhua i runga i te taumaha ngota mai i te wai matotoru (Mn=200~700), te haurua-totoka ware pi (Mn=1000~2000) ki te totoka ware pi mārō (Mn=3000~20000).

Ngā Tuhipoka
1) Ko ngā raraunga hangarau katoa kua whakahuatia i runga ake nei hei tohutoro māu.
2) e mihi ana ki ētahi atu whakatakotoranga hei matapakinga atu.
Te whakahaere
Ka mahia te mahi i roto i tētahi wāhi e pai ana te hau. Kakahuria ngā taputapu tiaki e tika ana. Ārai i te marara o te puehu. Horoia pai ō ringaringa me tō mata i muri i te mahi.
Ngā whakatūpato mō te whakahaere haumaru. Āraia te pā ki te kiri me ngā kanohi. Āraia te whakaputanga o te puehu me ngā hauhautanga. Whakaratohia he hauhautanga tika ki ngā wāhi e puta ai te puehu.
Rokiroki
Penapena ki te wāhi hauhautanga. Puritia te ipu kia katia rawatia ki te wāhi maroke, kia pai te hauhautanga. Te pāmahana rokiroki e taunakitia ana 2 – 8 °C
Ngā mōhiohio kawe waka
Kāore i te whakahaeretia hei rauemi morearea.
