Antiozonant PD-2 is a staining/discoloring antiozonant and antioxidant in rubber goods (including natural, SBR, NBR, and PBD).
It provides excellent protection against ozone, heat, oxidation, flex-cracking and metal ion (copper/manganese) poisoning.
Its use is restricted to dark colored articles where migratory staining can be tolerated.
Antiozonant PD-2 has a low melt point allowing excellent dispersion characteristics.
It can have an activating effect on sulfur cures, especially in polychloroprenes (Polychloroprenes normally use MPD-100 for ozone protection unless one of the above high diene polymers is present.
In this case, small amounts of PD-2 help protect the second polymer).
PD-2 is not recommended with peroxide cures.
Typical dosages of PD-2 are 1 to 2 phr. Up to 4 phr (or in combination with antioxidants like PANA, or Antioxidant 58) may be used in severe dynamic applications.
A petroleum wax (paraffin/microcrystalline blend) is recommended to aid static ozone resistance and help bring PD-2 to the rubber surface.
