Imikhiqizo
I-polyether ekhethekile – i-polyether ye-PET enesisindo esimaphakathi
Izakhiwo kanye Nokusetshenziswa
Kuwuketshezi ekamelweni lokushisa, okulula ukulisebenzisa nokuyicubungula. Izinga lokushisa lokushintsha kwengilazi elingu--80 ℃, ngokusebenza kahle kakhulu kwezinga lokushisa eliphansi, izakhiwo zemishini ze-elastomer ziseduze neze-PTMG.
Isetshenziswa kakhulu ekwakhiweni kwe-propellant eqinile, enezakhiwo ezinhle kakhulu zomshini zokushisa okuphansi kanye nobubanzi obukhulu bamazinga okushisa okusebenza.
Njengoba ikwazi ukuguquguquka kahle kwama-molecule, ingathatha indawo ye-PTMG ngesikhumba sokwenziwa esiguquguqukayo kanye noyinki wokunyathelisa; ingasetshenziswa kuma-glue anamathelayo angashisi kakhulu, ama-coating, ama-polyurethane elastomers njalo njalo.
