    Accelerator TBSI Powder - Sovereign Chemical Company

    TBSI is a primary amine-based accelerator which does not generates the nitrosamines and it can replace NOBS which is carcinogenic. The rubber added with TBSI can obtain good scorch safety and lower vulcanization rate, and show good curing reversion resistance, high modulus and lower heat generation, which optimizes adhesion between rubber and brass coated steel cord.

    Use of TBzTD as Noncarcinogenic Accelerator for ENR/SiO2

    Nitrosamines are generally generated from the rubber products during mixing, curing, and storage when using amine containing accelerators such as tetramethylthiuram disulfide (TMTD) [7, 20]. With this respect, the TBzTD, a fast curing accelerator with no secondary amine, has been developed to replace the TMTD, resulting in the nitrosamine free

    TBzTD and CBBS - alternative accelerators for reducing

    Many rubber accelerators generate secondary amines during mixing and curing operations, and thus can generate nitrosamines. MBS (2-morpholinothiobenzothiazole), a chemical that forms the secondary amine morpholine, generates the nitrosamine NMOR (N-nitrosomorpholine), while CBBS generates the primary amine cyclohexylamine, which does not yield
