Auala e fai ai le Polyether Polyol

Polyether Polyolse faia e ala i le taliina o le oxide organic ma le glycol.

Ole oxide fa'aola ole fa'aaogaina oleEthylene Oxide,Propylene Oxide,Butylene Oxide,Epichlorohydrin.

Glikol autu faʻaaogaina oEthylene Glycol,Propylene Glycol,Vai,Glycerine,Sorbitol,Sucrose,THME.

Polyols o lo'o i ai vaega fa'afofoga hydroxyl (OH) e tali atu i vaega ole isocyanate (NCO) i luga ole isocyanates e fai ai polyurethanes.

E tele ituaiga polyether polyols mopolyurethane.O mea PU ma faʻatinoga eseese e mafai ona maua i le tali atu i le va o le amataina ma le olefin polymerization.

E ala i le faʻaleleia o mea faʻapitoa a le PU poʻo le suia o le catalyst, e mafai ona faʻaleleia le faʻatinoga o le polyether.O nei faʻavae e aofia ai le 'ava malosi, 'ava malosi, tetrahydrofuran, ma polyether polyols aromatic, ma isi.

Tautinoga: O nisi o mea o loʻo maua mai le Initaneti, ma ua faʻamauina le puna.E na'o le fa'aaogaina e fa'amatala ai mea moni po'o manatu o lo'o ta'ua i lenei tusiga.E na'o le feso'ota'iga ma le a'oa'oina, ma e le'o mo isi fa'atauga fa'apisinisi.Afai e i ai so'o se soliga, fa'amolemole fa'afeso'ota'i mai e tape loa.
