Polyeter-ka khaaska ah - Miisaanka unugyadu dhexdhexaadka yahay PET polyeter
Guryaha iyo Isticmaalka
Waa dareere heerkulka qolka, kaas oo ku habboon in la isticmaalo lagana shaqeeyo. Heerkulka kala-guurka galaas ee -80 ℃, oo leh waxqabad heerkul hoose oo aad u wanaagsan, sifooyinka farsamada ee elastomerku waxay ku dhow yihiin kuwa PTMG.
Inta badan waxaa loo isticmaalaa qaab-dhismeed adag, oo leh sifooyin heerkul hoose oo heersare ah iyo heerkul ballaadhan oo shaqeynaya.
Dabacsanaanta molecular ee wanaagsan, waxay ku beddeli kartaa PTMG maqaar macmal ah oo dabacsan iyo khad daabacan; waxa loo isticmaali karaa xabag-xabag-hooseeya u adkaysta, dahaarka, elastomer polyurethane iyo wixii la mid ah.
