PRODUCT PROFILE
S.O.63Solvent Orange 63 — grade profile
Solvent Orange 63 (S.O.63) is a organic solvent dye for coloration in Plastics & masterbatch and Textiles & fibers. 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 GPPS, Polystyrene (PS), PMMA and ABS; PET, Rigid PVC and Synthetic fiber 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.
