Chemical Name: 1,3-Bis(citraconimidomethyl)benzene
Molecular Formula: C18H16N2O4
Molecular Weight: 324.33
CAS NO.: 119462-56-5
Appearance: White powder
Uses:
PK900 is an anti-reversion 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.Scorch and cure time are therefore not affected,thus to be added without making other compound or process modifications.
Storage:Stored it in a dry and cool area, avoid direct sun exposure
Package:25kg/bag
