Abstract
Nitrosamines (NA) reported to be found in rubber products vulcanized using conventional accelerators such as tetramethylthiuramdisulphide (TMTD) are carcinogenic. Tetra benzyl thiuramdisulphide (TBzTD) has been used in an efficient vulcanisation (EV) system to prepare rubber vulcanisates having properties comparable to the vulcanisate prepared using TMTD. TBzTD is reported to be non regulated and safe. The compound containing TBzTD shows better scorch safety. The novel safe vulcanisate shows comparable mechanical properties, crosslink density and improved aging resistance.
