Meatotino tau vailaau:

Polyether polyols o vaega autu ia e faʻaaogaina i le gaosiga o polyurethanes.

Polyether-based polyurethanes faʻaalia le faʻaleleia atili o le hydrolytic stability ma sili ona tetee atu i vai vaivai ma faʻavae pe a faʻatusatusa i polyester-based polyurethanes.

Polyether polyurethane e mafai ona vaevaeina i polyether foam vaivai, polyether foam malo ma elastomer ma polyether e tusa ai ma le faatinoga o oloa polyether.

Ae ui i lea, o polyether-based polyurethanes e sili atu ona faigofie ile UV radiation ma maua ai le le lelei o le tetee atu i suauu ma suauu pe a faatusatusa i polyester-based polyurethanes.

Talosaga:

O le faʻaaogaina o polyether faʻaaogaina i le PU e sili atu i le 80%.Polyether polyurethane e mafai ona fa'avasegaina

Polyether Polyol(PPG),Polymeric Polyol (POP),Polytetramethylene ether glycol (PTMEG, e taʻua foi polytetrahydrofuran polyol) e tusa ai ma le amataga.

Polyether polyols e masani ona faʻaaogaina i le PU faʻamaʻa faʻamaʻa, faʻafefe vaivai, ma faʻafefeteina oloa.
