SF50 is a product with improved cost-to-performance ratio recommended to replace SnS based compounds

SF50
Sulfides are chemically active additives that protects from oxidation the sensitive components of the formulations, like phenolic resins and graphite.
SF50 is 1:1 composite of tin (II) and iron (II) sulfides. Because of its unique microstructure, we can modify their oxidation temperature and match the oxidation range of SnS.
