Physical Properties
Melting Range 268 - 275 °C
SolubilitySoluble in acetic acid and dimethylacetamide
Insoluble in water
  • Nylostab S-EED FF provides excellent stability during processing and use to filled and not filled polyamides. It enhances color affinity and dispersion for pre-metallized dyes, acid dyes as well as for pigments, enabling economical, ecological and deep coloration.

  • Nylostab S-EED FF can effectively be combined with Hostanox P-EPQ and Hostavin VSU for further boosting color and UV stability of polyamides.

  • Nylostab S-EED FF can be incorporated in-situ during polymerization process or as a concentrate during polyamides compounding processes.
