Iimveliso
I-polyether ekhethekileyo – i-polyether ye-PET enobunzima obuphakathi
Iipropati kunye nokusetyenziswa
Ilulwelo kubushushu begumbi, olulula ukulusebenzisa nokuyicubungula. Ubushushu bokutshintsha kweglasi obuyi--80 ℃, kunye nokusebenza kakuhle kobushushu obuphantsi, iipropati zoomatshini ze-elastomer zisondele kwezo ze-PTMG.
Isetyenziswa kakhulu kwiifomyula ze-propellant eziqinileyo, ezineempawu ezintle kakhulu zoomatshini ezinobushushu obuphantsi kunye nohlobo olubanzi lobushushu bokusebenza.
Ngokuguquguquka okuhle kweemolekyuli, ingathatha indawo ye-PTMG kwi-inki yesikhumba esenziweyo esiguquguqukayo kunye ne-inki yokuprinta; ingasetyenziswa kwi-adhesives ezimelana nobushushu obuphantsi, ii-coating, ii-polyurethane elastomers njalo njalo.
