NOBS-60 Pre-Dispersed MBTS Accelerator

NOBS-60 is a 60% dispersion of 2,2'-dithiobisbenzothiazole on polymer carrier for even distribution in rubber mixes. Despite dispersion, the active ingredient's benzothiazole structure qualifies it under HTS 2934.20.10.00 as the principal compound. Used in automotive belts and hoses for controlled vulcanization.
