Usage:
Granular Sulphur is mainly used in the manufacture of compound semiconductors, photoelectric devices
and glass semiconductor elements and as calibration speciment in analysis. And also it can restrain
effectively that the sulfur blooms in the products, eliminate the phenomenon that sulfur agglomerated.
It's also used for dyeing and winding dyeing on cotton,viscose,polyving aloohd fibre and polyester,
polyamide fibre,especially used for rolling dyeing.It is uniform and stable in color, good permeability
.when dyeingf without any fragile treatment.It is also used for dyeing on leather and original viscose
fibre.
