  • Applications

    Accelerator CZ, CAS 95-33-0, is a sulfur vulcanization accelerator for rubber and elastomers, used to shorten cure time and improve the mechanical properties of the vulcanized network; typical applications include tires and other rubber products such as hoses, gaskets, and seals; it is also used in elastomer-based adhesive and sealant formulations to accelerate cure and control the vulcanization process; in plastics and polymer blends, CZ can be used as an accelerator for elastomer-rich systems and blends to tune cure behavior; it may be considered for coating or encapsulation applications based on rubber/elastomer to improve durability and chemical resistance, depending on formulation and local regulations.
