ABSTRACT:
The current invention relates to the use of tetrabenzylthiuram disulfide/urea curative package for thermosetting rubber elastomers in an environmentally sound method of eliminating undesirable nitrosamines. The unique curative package synergistically increases the cure rate and physical properties of the elastomeric compound while reducing the amount of accelerator needed for vulcanization.
