Badeecadaha
Polyeter-ka Gaarka ah ee PET-ka Miisaanka Molecular-ka ee Hoose
Guryaha iyo Isticmaalka
Waa dareere heerkulka qolka, kaas oo ku habboon in la isticmaalo oo la farsameeyo. Heerkulka kala-guurka galaaska ee -80 ℃, oo leh waxqabad heer-kulka hooseeya oo aad u fiican, sifooyinka farsamada ee alaabteeda elastomer iyo PTMG oo u dhow PTMG, ayaa beddeli kara PTMG jawiga heerkulka hooseeya ee adag.
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.
