Dusantox® IPPD is one of the most effective accessible antidegradants available for elastomers. It acts as an effective long-term antiozonant and antioxidant giving vulcanizates high resistance against atmospheric, thermooxidative and oxidative ageing. It improves flex fatigue resistance significantly and suppresses the effects of rubber poisons. Dusantox® IPPD provides excellent protection against ozone in static as well as in dynamic conditions. It is possible to improve more the ozone resistance of vulcanizates under both static and combined (dynamic and static) conditions by addition of suitable microwaxes. Dusantox® IPPD is effective in NR, IR, SBR, BR, NBR, CR and in compounds based on their combinations. In order to reach higher protection levels of vulcanizates it is recommended to use Dusantox® IPPD in combination with Dusantox® 86 (cumylated diphenylamine) or other antioxidants of phenylnaphthylamine, imidazole and TMQ type. Partly activates vulcanization process of NR, IR, especially CR. It causes expressive colouring and contact staining of vulcanizates.
