DTPD features outstanding ozone resistance. Its flex cracking resistance is comparable to Antioxidant 4010NA or 4020, and superior to Antioxidant AD.

When blended with an equal amount of Antioxidant 4020 or 4010NA, DTPD(3100) delivers optimal antiozonant performance and significantly extends tire service life due to the synergistic effect between the two antioxidants.

Antioxidant 4020 and 4010NA provide short-term initial protection, while DTPD offers long-term durable protection.
