Specialty polyether - yepakati molecular uremu PET polyether
Properties uye Mashandisirwo
Iyo iri mvura pane tembiricha yekamuri, iyo iri nyore kushandisa nekugadzirisa. Girazi rekuchinja tembiricha ye -80 ℃, ine yakanakisa kudzika-tembiricha kuita, iyo mechaniki zvimiro zve elastomer iri padyo neiyo yePTMG.
Inonyanya kushandiswa mune yakasimba propellant formulations, ine yakanakisa yakaderera-tembiricha michina zvivakwa uye yakawanda yekushanda tembiricha.
Iine yakanaka mamorekuru kuchinjika, inogona kutsiva PTMG mune inochinjika chakagadzirwa dehwe uye ingi yekudhinda; inogona kushandiswa mune yakaderera-kupisa-inodzivirira adhesives, coatings, polyurethane elastomers uye zvichingodaro.
