The Compounding and Vulcanization of Rubber,he compounder. Traditionally, the compounder has been a trained chemist or chemical engineer. This background is necessary since some of the processes involve complicated chemical reactions, of which vulcanization is the most important. In addition, chemical analysis of the raw materials and of the

Ethylene-Propylene Rubber,tion began only in 1963, EPM/EPDM rubber is now the fastest growing elastomer (ca. 6% per year), and there are presently five manufacturers in the United States, four in Europe, and three in Japan. The reasons for its rapid growth are its excellent properties, especially in an ozone environment, and

Butyl and Halobutyl Rubbers,vatives, chloro- and bromo-, were introduced in the early 1960’s and have been commercially available since then. The halogenated derivatives of butyl rubber provide greater vulcanization flexibility and enhanced cure compatibility with other, more unsaturated general-purpose elastomers. Butyl polym
