    Rubber and tire manufacturers rely on Cure-Rite® Rubber Accelerators as a key part of the rubber vulcanization package. Cure-Rite® accelerators control the rate of vulcanization, which can improve rubber manufacturing productivity and ensure the development of desirable properties―such as strength, elasticity, modulus, and oxidation stability―prior to curing.

    Common Vulcanization Accelerators

    Vulcanization Accelerator. is a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Vulcanization accelerators can be classified as primary and secondary accelerators. Important primary accelerators include thiazoles and sulfenamides.

    Vulcanization

    Vulcanization (British: Vulcanisation) refers to a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice; however, it has also grown to include the hardening of other (synthetic) rubbers via various means.

    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

    Vulcanization refers to a specific curing process of rubber involving high heat and the addition of sulfur. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms.
