APPLICATION:
TMTM can extremely accelerate vulcanization rate of natural and synthetic rubber and has good scorching safety. The activity can be improved by combination of alkaline accelerators such as aldehyde-amines and guanidines. br/> As a secondary accelerator with sulfenamides and thiols, TMTM has important applications in technically. Low-sulfur vulcanization can provide excellent heat aging resistance for vulcanizates.
