Iimveliso
I-Specialty Polyether-Low Molecular Weight PET Polyether
Iipropati kunye nokusetyenziswa
Ilulwelo kubushushu begumbi, nto leyo elula ukuyisebenzisa nokuyicubungula. Ubushushu bokutshintsha kweglasi obuyi--80 ℃, obusebenza kakuhle kubushushu obuphantsi, iipropati zoomatshini zeemveliso zayo ze-elastomer kunye ne-PTMG ezikufutshane ne-PTMG, zingathatha indawo ye-PTMG kwimeko-bume enzima yobushushu obuphantsi.
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.
