1,3-Bis(Citraconimidomethyl)Benzene

1,3-Bis(Citraconimidomethyl)Benzene is an antireversion agent which provides long term heat stability in sulfur vulcanized compounds by substituting stable, flexible carbon-carbon crosslinks for the sulfur crosslinks that are destroyed by reversion in the mold or during product service life. It is used in most sulfur vulcanized polymers such as NR, IR, SBR, BR or blends to provide improved reversion resistance on overcure. It is used to allow the use of higher curing temperature for improved productivity without sacrificing performance properties. It ‘s not reactive during the initial stages of vulcanization.

DURALINK HTS

DURALINK HTS increases the retention of physical and dynamic properties on overcure, high temperature cure and during service by providing a hybrid crosslink which combines excellent thermal stability with dynamic flexibility. DURALINK HTS used in conjunction with conventional or Semi-E.V. sulfur-based curing systems in NR, IR, SBR and blends. DURALINK HTS may be used as a bonding promoter for rubber/brassed steel adhesion.
