    Raw rubbers are widely used in the industrial field such as materials for tire and nontire. The review describes the structure, characterization and manufacturing method of natural rubber, general purpose rubber such as styrene-butadiene rubber,butadiene rubber, isoprene rubber, butyl rubber, and special purpose rubber such as ethylene-propylene rubber, acrylonitrile-butadiene rubber, hydrogenated acrylonitrile-butadiene rubber, chloroprene rubber, acrylic rubber, silicone rubber,fluoro rubber. Recent trends on several kinds of catalyst systems and modifications of those rubbers are reviewed, further masticating behavior of those rubber are introduced.

    Vulcanizing agents can be classified roughly into sulfur and sulfur donor. The sulfur includes powdered sulfur, surface treated sulfur, precipitated sulfur, colloidal sulfur and insoluble sulfur. The sulfur donor includes dithiodimorpholine, alkylphenol disulfide, polysulfide and some accelerators. In this chapter, their characteristics are explained. In addition, the results of using co-curing agent with the combination of sulfur vulcanization are described.

  • Vulcanization Accelerators
    Tomoyuki KOMATSU

    Vulcanization accelerators are important for sulfur vulcanization. Sulfur vulcanization is performed by heating the rubber to which sulfur was added. But, it proceeds very slowly in the absence of a vulcanization accelerator, and the properties of the vulcanized rubber are inferior. Vulcanization accelerator promotes the vulcanization reaction and improves the quality of the rubber. This report describes fundamentals of the vulcanization accelerator.
