Sulfur vulcanizing agents S-80 and IS-80, although both employed in the rubber vulcanization process, represent two distinct types of vulcanizing agents.

Sulfur Vulcanizing Agent S-80:

This name typically refers to pre-dispersed sulfur compound S-80, a form of sulfur that has undergone specialized treatment to create a pre-dispersed vulcanizing agent. The technology of sulfur pre-dispersion enhances the distribution of sulfur within rubber, leading to a more uniform vulcanization process, which in turn contributes to improved physical and mechanical properties as well as the durability of rubber products. S-80 likely denotes a sulfur dispersion with a specific formulation or advanced dispersion technique.

Sulfur Vulcanizing Agent IS-80:

This is inferred to be Insoluble Sulfur Vulcanizing Agent IS-80, referring to a highly polymerized form of sulfur. Unlike ordinary sulfur, IS-80 is insoluble in common solvents used in rubber processing under normal conditions and exhibits superior dispersibility and storage stability. During rubber vulcanization, IS-80 distributes more evenly throughout the rubber matrix, facilitating an optimized cross-linking structure in the vulcanizate, thereby enhancing properties such as the strength, heat resistance, and fatigue endurance of rubber products.

In summary, the primary distinctions between the two lie in the form of sulfur and their respective vulcanization outcomes:

Sulfur Vulcanizing Agent S-80 emphasizes the pre-dispersion characteristics of sulfur, aiming to address the issue of uneven sulfur dispersion during rubber mixing. On the other hand, Sulfur Vulcanizing Agent IS-80 highlights its identity as insoluble sulfur, a vulcanizing agent differing chemically and physically from standard sulfur, making it more suitable for applications where high uniformity in vulcanization and superior product performance are paramount.
