  • Can santoflextm 6PPD be used for oxidation resistance?
  • SantoflexTM 6PPD can also be used for oxidation resistance alone. Its antioxidant performance is maximized at 0.5 phr. Higher levels actually reduce antioxidant protection even though ozone and flex fatigue resistance increase with higher levels.
  • Why is Santoflex 6PPD better than IPPD?
  • Santoflex™ 6PPD gives better long term fatigue resistance and ozone protection than IPPD. Due to its specific molecular structure and higher rubber solubility, it is less affected by environmental variables, such as heat or leaching, leading to greater durability.
  • Does santoflextm 6PPD protect polychloroprene?
  • It will also help protect polychloroprene but can reduce bin storage stability. To stabilize solution or emulsion polymerized elastomers add 0.3 to 0.6% (dry basis) of SantoflexTM 6PPD. For detailed information on toxicological properties and handling precautions please refer to the current Safety Data Sheet.
  • Should TMQ be added to Santoflex® 6PPD?
  • Note: No PPD should be used at levels less than 1 phr in surface applications, as the ozone cracking pattern produced can lead to catastrophic failure. Adding TMQ will maintain a compound's resistance to oxidation as well as protect SantoflexTM 6PPD from oxidizing, thus further enhancing long term performance.
