| Anitiozonant PD-1 |
 |
Antiozonant PD-1 is a n-isopropyl-n'-phenyl-p-phenylene diamine.
It is recommended for use in rubber compounds as a general purpose antiozonant with antioxidant properties.
It also exhibits copper and manganese inhibitor properties.
Antiozonant PD-1 is effective as an antioxidant, antiozonant and antiflexcracking inhibitor at 1.0 - 3.5 phr levels in natural rubber, SBR, NBR, and polybutadiene. In polychloroprene, it is effective at a lower concentration of 0.4 - 1.5 phr.
Antiozonant PD-1 does discolor and stain and could exhibit a slight viscosity stiffening depending on type of carbon black used.
It also activates cure systems using CBTS and MBTS. |
