Iimveliso
I-Specialty Polyether-Low Low Molecular Weight PET Polyether
Iipropati kunye nokuSetyenziswa
Ilulwelo kwiqondo lobushushu begumbi, elilungele ukusetyenziswa kunye nokusebenza. Ubushushu beGlass transition ye -80 ℃, kunye nokusebenza okubalaseleyo kobushushu obuphantsi, iipropathi zomatshini zeemveliso zayo ze-elastomer kunye ne-PTMG ekufutshane ne-PTMG, inokutshintsha indawo ye-PTMG kwindawo enobushushu obuphantsi.
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.
