Zvigadzirwa
Polyether Yakakosha-Yakaderera Molecular Weight PET Polyether
Zvivakwa uye Mashandisirwo
Iri mvura patembiricha yemumba, zviri nyore kushandisa uye kugadzirisa. Tembiricha yekuchinja kwegirazi ye -80 ℃, ine mashandiro akanaka ekupisa kwakaderera, hunhu hwemuchina hwezvigadzirwa zvayo zve elastomer uye PTMG iri pedyo nePTMG, zvinogona kutsiva PTMG munzvimbo ine tembiricha yakaderera.
Nekuchinjika kwakanaka kwemamorekuru, inogona kutsiva PTMG neganda rekugadzira rinochinjika uye inki yekudhinda; inogona kushandiswa mumaglues anodzivirira kupisa kwakanyanya, macoatings, polyurethane elastomers nezvimwewo.
