- Applications
- ST-FS-SA has very low reactivity. This is a major advantage in acid-sensitive polymers, such as PET, PC which conventional antimony trioxide synergist can promote depolymerization during processing.
- ST-FS-SA has relatively low refraction index. It offers little opacity to the plastics. Another desirable feature of ST-FS-SA is exceptionally low tint strength which permits color pigments to exercise their maximum effect. Excellent blacks, greens, maroons, wines and other reds can be produced with less pigment than previously required. In many cases, the coloring costs of compound can be lowered significantly by using ST-FS-SA.
