Polyeter-ka Gaarka ah-Miisaanka Molecular Low 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 alaabteeda elastomerka iyo PTMG ee u dhow PTMG, waxay bedeli kartaa PTMG jawiga heerkul hoose ee adag.
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.
