Iimveliso
I-Specialty polyether-i-molecular weight medium PET polyether
Iipropati kunye nokuSetyenziswa
Ilulwelo kwiqondo lobushushu begumbi, elilungele ukusetyenziswa kunye nokusebenza. Ubushushu beglasi yenguqu ye -80 ℃, kunye nokusebenza okubalaseleyo kobushushu obuphantsi, iipropathi zomatshini ze-elastomer zisondele kwezo ze-PTMG.
Ikakhulu isetyenziswa kwimiqulu eqinileyo ye-propellant, eneempawu ezibalaseleyo zobushushu obusezantsi kunye noluhlu olubanzi lwamaqondo obushushu okusebenza.
Ngokuguquguquka okuhle kwemolekyuli, inokutshintsha i-PTMG kwisikhumba sokwenziwa esibhetyebhetye kunye ne-inki yokuprinta; inokusetyenziswa kwizinto zokuncamathelisa ezikwaziyo ukumelana nobushushu obuphantsi, icoatings, polyurethane elastomers njalo njalo.
