The morphological analysis of the fibers revealed a WebAs for the scorch time, Ts2, each blends has almost similar scorch time except for Blend 9 which consist of 161 phr of BRR. Since Blend 6 is only BRR alone, a longer scorch time is needed so that the BRR to be partly vulcanized. Scorch time is the period before vulcanization and it is necessary that vulcanization does not start until scorching ...
