Post vulcanization stabilizer

Reversion characteristics of NR are of great concern. Lot of novel chemicals have been introduced to increase the reversion resistance of NR. Examples of these are zinc soap activator (Structol-A73), silane couphng agent (Si-69), anti-reversion agent (Perkalink 900), and post-vulcanization stabilizer (Durahnk HTS and Vulcuren KA 9188 Figure 32.7). These materials will enhance the life of the tire, enable the users for more retreading, and thereby reduce the material demand. " ...
