basic introduction
Insoluble sulfur, molecular formula: Su, is a non-toxic, flammable yellow powder, named because it is insoluble in carbon disulfide. It is made by thermal polymerization of ordinary sulfur. The number of sulfur atoms in the molecular chain is as high as 108 or more. It has the viscoelasticity and molecular weight distribution of a polymer. Therefore, it is also called elastic sulfur or polymerized sulfur, which is an inorganic polymer chemical raw material.
