Badeecadaha
Polyeter-ka Gaarka ah - polyeter-ka PET-ka miisaankiisu dhexdhexaad yahay
Guryaha iyo Isticmaalka
Waa dareere heerkulka qolka, kaas oo ku habboon in la isticmaalo oo la farsameeyo. Heerkulka kala-guurka galaaska waa -80 ℃, oo leh waxqabad heer-kul hoose oo heer sare ah, sifooyinka farsamada ee elastomer-ka ayaa u dhow kuwa PTMG.
Waxaa inta badan loo isticmaalaa qaacidooyinka adag ee kiciya, oo leh sifooyin farsamo oo heerkul hooseeya oo heer sare ah iyo heerkul hawlgal oo ballaaran.
Iyada oo leh dabacsanaan wanaagsan oo molecular ah, waxay beddeli kartaa PTMG maqaar macmal ah oo dabacsan iyo khad daabacan; waxaa loo isticmaali karaa dhejisyada heerkulka hooseeya, dahaarka, polyurethane elastomers iwm.
