hydroxy rubber accelerator zdibc oil rubber accelerator
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.

Formation and occurrence of nitrosamines in food. - PubMed
Nitrosamines are formed by reaction of secondary or tertiary amines with a nitrosating agent. In foods, the nitrosating agent is usually nitrous anhydride, formed from nitrite in acidic, aqueous solution. Food constituents and the physical make-up of the food can effect nitrosamine formation.
