Specialty Polyether-Yakaderera Molecular Weight PET Polyether
Properties uye Mashandisirwo
Iyo iri mvura pane tembiricha yekamuri, iyo iri nyore kushandisa nekugadzirisa. Girazi shanduko tembiricha ye -80 ℃, ine yakanakisa kudzika-tembiricha kuita, iyo mechaniki zvivakwa zve elastomer zvigadzirwa uye PTMG padyo nePTMG, inogona kutsiva iyo PTMG munzvimbo ine hutsinye hwekudzikira.
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.
