What is a sulfur donor?
Sulfur donors are of particular interest to the rubber industry, because they make it possible to fulfill special requirements. These organic compounds contain sulfur in a thermally labile form. Under normal curing conditions, free sulfur is released which, in contrast to normal sulfur, mainly forms mono- and di-sulfidic bridges.

What are Utra/secondary accelerators?
t popular ultra/secondary accelerators are the dithiocarbamates and thiurams. The u tra/secondary accelerators often produce scorchy, very fast curing compounds. Their major functions are that they oduce increased cure rate (i.e. raise the modulus) and shorten scorch times. Quite frequently they are paired with a primary acce
