Specialty elastomers vulcanization agents

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. 

A wide variety of vulcanization agents are used in the rubber industry. For specialty elastomers, peroxide cross-linking is probably the most widely used and fastest growing system. The various peroxides available for cross-linking and newer developments in this area will be reviewed. Other vulcanization agents for specialty elastomers will also be presented. 

This book defines specialty elastomers as heat-, oil-, fuel-, and solvent-resistant polymers. Each chapter examines individual elastomers in terms of development history, chemical composition, structure, and properties as well as processing methods, applications, and commercially available products. Covering their applications in the rubber, energy, chemicals, and oil industries, the book also discusses the use of antioxidants, antiozonants, vulcanization agents, plasticizers, and process aids for specialty elastomers. The concluding chapter details considerations and relevant processes—such as molding operations—involved in designing application-specific rubber components. 

In addition to the information on the specialty elastomers, chapters on the more important ingredients used with them are included. These are plasticizers, vulcanization agents, antioxidants and antiozonants, and process aids.
