Eastman Santoflex 44PD is an diamine-based antioxidant particularly effective for gasoline produced by cracking or pyrolysis (high olefin content gasoline) and as an effective polymerization inhibitor.
Santoflex 44PD also acts as a high activity antiozonant to protect natural and synthetic elastomer compounds, particularly in static applications for compounds containing no wax.
