CHEMICAL NAME: 1,3-Bis(citraconimidomethyl)benzene
CAS NO.: 119462-56-5
Equivalent to: Perkalink 900
STRUCTURE 
Nurvinox PK900 provides long term heat stability in sulfur vulcanized compounds by substituting stable, flexible carbon-carbon crosslink for the sulfur crosslink 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 over-curing. 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, scorch and cure time are therefore not affected, thus to be added without making other compound or process modifications.
