  • classification of rubber accelerator

    Classification of rubber accelerator

    Classification of commonly used accelerator are the following. The rubber accelerator can be divided into eight categories according to the structural classification of the accelerator: thiazole (M, DM), sulfonamide (CZ, NOBS, DZ),thiuram (of TMTD, TMTM), thiourea (NA-22), dithiocarbamate salts (ZDMC, ZDC), aldehyde amines (H), guanidine (D), xanthate class(ZIX).

    A Scheme for Accelerator Classification | Rubber Chemistry

    MUCH has been written about the constitution and chemical behavior of vulcanization accelerators. Theories have been advanced regarding the mechanism of vulcanization effected with their aid. Yet even the authors of such papers—presumably best qualified to interpret their contents—would hesitate to predict, from chemical structure, many of

    Accelerator, in the rubber industry, is added with a curing agent to speed the vulcanization. Accelerators contain sulfur and nitrogen like derivatives of benzothiazole and thiocarbanilides. The popular accelerators are sulfenamides (as a delayed-action accelerators), thiazoles, thiuram sulfides, dithocarbamates and guanidines.
