Understanding the Composition of a Nitrile (Buna-N) Rubber

Changing the levels of accelerators can improve compression set and speed the cure process so molded parts take less time in the mold. It is always the concern that the scorch time (time the rubber compound begins to cure) is not reduced so much that the operator cannot load the rubber charge into the mold fast enough to prevent defects.
