Mono propylene glycol
Fa'amatalaga o oloa
O se vai e leai se lanu ma le viscosity tumau ma lelei le mitiia o le vai.
E toetoe a leai se manogi, e le mu ma oona itiiti.O lona mole mole mamafa o le 76.09.O lona viscosity (20oC), malosi vevela faapitoa (20oC) ma le latent vevela o vaporization (101.3kpa) e faasologa 60.5mpa.s, 2.49KJ/(kg. oC) ma 711KJ/kg.
E mafai ona faʻafefiloi ma fofo i le ava malosi, vai ma vailaʻau eseese.
O le propylene Glycol o le mea mataʻutia mo le sauniaina o le resini polyester unsaturated, plasticizer, luga o le mea e galue malosi, emulsifying agent ma demulsifying agent.
E mafai foʻi ona faʻaaogaina e fai ma faʻalavelave faʻafefe, vailaʻau faʻamaʻi mo fualaau aina, faʻamaʻi aisa ma susū faʻasao faʻasao mo tapaa.

Fa'aaogāga
(1) Propylene glycol o loʻo faʻaaogaina e fai ma mea mata mo resins, plasticizers, surfactants, emulsifiers ma demulsifiers, faʻapea foʻi ma mea faʻamaʻi ma vevela.
(2) Propylene glycol o loʻo faʻaaogaina e pei o le kesi chromatography vai tumau, solvent, antifreeze, plasticizer ma dehydrating agent.
(3) Propylene glycol e masani ona faʻaaogaina mo le suʻeina o mea manogi o mea manogi eseese, pigments, preservatives, vanilla pi, kofe kofe granule, tofo masani ma isi.O se mea e fa'asusu ma fa'amalulu mo lole, falaoa, mea'ai afifi, sisi, ma isi.
(4) E mafai foʻi ona faʻaaogaina e fai ma sui anti-mildew mo saimini ma faʻatumu le autu.Fa'aopoopo le 0.006% ile susu soya, e mafai ona le suia le tofo pe a fa'avevela, ma fai ai le pa'epa'e pa'epa'e ma le iila pi'i.
