Vulcanizable elastomeric formulation are disclosed. The formulations comprise at least one elastomer; a vulcanizing agent comprising cyclododecasulfur; and a prevulcanization inhibitor, present in an amount, for example, from about 0.01 phr to about 10 phr. The formulations, when vulcanized, provide articles that exhibit improved durability.

Durable elastomeric compositions employing cyclododecasulfur as a vulcanizing agent

A vulcanizing composition useful for the vulcanization of vulcanizable formulations is disclosed. The vulcanizing composition includes a vulcanizing agent which in turn includes a cyclododecasulfur compound. A cyclododecasulfur compound characterized by a DSC melt point onset of between 155&#xb0; C. and 167&#xb0; C. when measured at a DSC heat rate of 20&#xb0; C./minute is also disclosed.

Vulcanizing composition containing cyclododecasulfur and improved cyclododecasulfur compound

Processes for forming a vulcanizable elastomeric formulation are disclosed. The processes include the steps of mixing an elastomer with a vulcanizing agent to form a vulcanizable elastomeric formulation that includes the vulcanizing agent dispersed in the elastomeric compound, wherein the vulcanizing agent includes a cyclododecasulfur compound. A process for forming a vulcanized elastomeric article is also described.
