Elastomer crosslinking (vulcanization) involves tying together loosely held molecular chains into a three-dimensional network structure of polymeric chains capable of supporting a sustained load (stress) or withstanding a constant deformation (strain). Physical properties imparted to an elastomeric polymer due to crosslinking include high tensile strength, low compression set, recoverable elongation, high tear energy and improved dynamic performance (ref. 1). Achieving optimum physical properties through vulcanization depends on the elastomer, chemical additives and vulcanization system. Chemical additives known as coagents are used in conjunction with radical cure systems ...
