PRODUCT PROFILE
S.R.197Solvent Red 197 — grade profile
Solvent Red 197 (S.R.197) is a organic 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 300 °C. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Polystyrene (PS), PMMA, ABS and Rigid PVC; PET are listed for evaluation.
Selection focus
Confirm polymer compatibility, transparency, dissolution, actual melt temperature, loading, and migration and light-fastness requirements in the finished article.
