Nonsulfur vulcanizing agents

Sulfur crosslinks are thermally not as stable as some other types of crosslinks formed from the use of either peroxide or resin curatives. Sometimes these more expensive curative packages have to be used in place of sulfur-based systems to achieve the higher temperature resistance or better compression set resistance properties for the rubber compound.

Nonsulfur Vulcanizing Agents. Many high performance specialty elastomers do not contain diene moieties in their molecular structure and therefore cannot be sulfur-cured. These elastomers require cross-linking agents capable of reacting with the specific functional group(s) contained by the specific elastomer. Some common nonsulfur curatives include peroxides, difunctional resins, and metal oxides. 

Use Nonsulfur vulcanizing agent, in tire-curing bags, gaskets, and wire insulation to impart heat resistance.
