Imikhiqizo
I-Specialty polyether - isisindo samangqamuzana aphakathi kwe-PET polyether
Izakhiwo kanye nokusetshenziswa
Iwuketshezi ekushiseni kwegumbi, okulula ukuyisebenzisa nokuyicubungula. Izinga lokushisa lokushintsha kwengilazi elingu -80 ℃, ngokusebenza okuhle kakhulu kwethempelesha ephansi, izici zomshini ze-elastomer ziseduze nalezo ze-PTMG.
Isetshenziswa kakhulu ekwakhiweni kwe-propellant eqinile, enezakhiwo ezinhle kakhulu zemishini yezinga lokushisa eliphansi kanye nezinhlobonhlobo zamazinga okushisa okusebenza.
Ngokuguquguquka okuhle kwamangqamuzana, ingangena esikhundleni se-PTMG esikhumbeni sokwenziwa esiguquguqukayo kanye noyinki wokuphrinta; ingasetshenziswa ezintweni ezinamathelayo ezimelana nokushisa okuphansi, okokugqoka, ama-polyurethane elastomers nokunye.
