Vulcanizing agents
As previously described, vulcanizing agents are chemicals which produce a three dimensional structure by formation of crosslinks between the long chain segments of the rubber molecules This provides the elastic properties observed
Sulfur and sulfur donors
Sulfur is the most common vulcanizing agent used for the widely used diene containing elastomers such as natural rubber, SBR and polybutadiene. Rubbermakers sulfur is a rhombic form existing as a cyclic or eight member ring structure. Insoluble sulfur is an amorphous polymeric form with molecular weights of 100,000-300,000. Because this material is insoluble in rubber ...
