Zvigadzirwa
Polyether yakakosha - PET polyether ine huremu hwepakati
Zvivakwa uye Mashandisirwo
Imvura patembiricha yemumba, zviri nyore kushandisa uye kugadzirisa. Tembiricha yekuchinja kwegirazi ye -80 ℃, ine mashandiro akanaka ekupisa kwakaderera, hunhu hwe elastomer hwakafanana nehwe PTMG.
Inonyanya kushandiswa mumhando dzakasimba dzepropellant, ine hunhu hwakanaka hwemakanika husingapise tembiricha uye tembiricha dzakasiyana siyana dzekushanda.
Nekuchinjika kwakanaka kwemamorekuru, inogona kutsiva PTMG neganda rekugadzira rinochinjika uye inki yekudhinda; inogona kushandiswa mumaglues anodzivirira kupisa kwakanyanya, macoatings, polyurethane elastomers nezvimwewo.
