Vulcanization ScienceDirect
Jan 01, 2005· Vulcanization, thus, is a process of chemically producing network junc- tures by the insertion of crosslinks between polymer chains. A crosslink may be a group of sulfur atoms in a short chain, a single sulfur atom, a carbon to carbon bond, a polyvalent organic radical, an ionic cluster, or a polyvalent metal ion.
The first process, called Pressure Vulcanization involves heating the rubber with sulfur under pressure, with a temperature of 150C. The second process, called Free Vulcanization, simply involves passing very hot steam or air through the rubber. Eight hours of curing time is necessary for vulcanization to complete, although, chemical
