Kev taw qhia thiab kev siv ntawmCAS:542-28-9|delta-Valerolactone
Delta-Valerolactone yog ntau hom tshuaj nruab nrab thiab siv nyob rau hauv ntau qhov chaw. Nws yog tsuas yog siv los hloov caprolactone hauv inks thiab txheej additives. delta-Valerolactone hloov caprolactone hauv inks thiab txheej additives. Cov inks thiab coatings tsim muaj qhov zoo ntawm kev txo cov viscosity zoo dua thiab tsis-solidification ntawm qhov kub thiab txias dua li cov uas tsim los ntawm caprolactone nkaus xwb.
