Rn. Datta et Faa. Ingham, IMPROVING TREADWEAR WITHOUT INCREASING HEAT BUILD UP BY USING 1,3-BIS(CITRACONIMIDOMETHYL)BENZENE, Kautschuk und Gummi, Kunststoffe, 51(10), 1998, pp. 662
The antireversion agent 1,3-bis(citraconimidomethyl) benzene (Perkalin
k 900) reduces heat build up in vulcanizates under dynamic conditions,
It functions by a crosslink compensation mechanism that maintains com
pound physical and dynamic properties on overcure or during service, T
he conventional approaches to improving treadwear - partial replacemen
t of NR with BR, increased carbon black level or use of higher reinfor
cing blacks - lead to increased heat build up. This has limited the ap
plication of these approaches in practice, However, by incorporating P
erkalink 900 together with these compound modifications the increased
heat build up can be prevented, thus allowing improvements in treadwea
r to be realized. This is shown by laboratory data.
