Fa'apitoa Polyether-Low Molecular Weight PET Polyether
Meatotino ma Fa'aoga
E sua i le vevela o le potu, lea e faigofie ona faʻaoga ma faʻagasolo. O le vevela suiga o tioata o le -80 ℃, faʻatasi ai ma le lelei o le faʻatinoga o le vevela, o mea faʻainisinia o ana oloa elastomer ma PTMG latalata ile PTMG, e mafai ona suitulaga i le PTMG i se siosiomaga vevela maualalo.
Faatasi ai ma le fetuutuunai lelei mole mole, e mafai ona sui ai le PTMG i le paʻu faʻaoga faʻafefete ma le vaitusi lolomi; e mafai ona faʻaaogaina i mea faʻapipiʻi maualalo-vevela, paʻu, elastomers polyurethane ma isi.
