摘要: 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.

摘要: 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° C. and 167° C. when measured at a DSC heat rate of 20° C./minute is also disclosed.

摘要: 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.
