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 a nitrosamine.
