PRODUCT PROFILE
S.Y.93Solvent Yellow 93 — grade profile
Solvent Yellow 93 (S.Y.93) is a pyrazolone solvent dye for coloration in Plastics & masterbatch. Grade selection should be verified for polymer compatibility, actual processing temperature, target transparency and migration requirements; the data below is limited to values supported by published sources.
Published screening data includes published heat reference 280 °C. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include GPPS, Polystyrene (PS), PMMA, ABS, PET and Rigid PVC.
Selection focus
Confirm polymer compatibility, transparency, dissolution, actual melt temperature, loading, and migration and light-fastness requirements in the finished article.
