    1. Rubber Antioxidant DTPD has good resistance to ozone, excellent anti-flex cracking performance.
    2. Application:
      1. Vestox™ DTPD is para phenylene diamine anti-aging agent, chloroprene adhesive antiozonidate. It is high efficient anti-aging agent in tyre industry and can also be applied to various rubber products.
    3. 2. Vestox™ DTPD is with good long-term performance especially when it is combined with antioxidant 6PPD (4020) or IPPD (4010NA), which is the best ozone resistance system to improve lifespan of the tyre. It is because that the two types is with synergistic effect to phenylene diamine, the antioxidant 6PPD (4020) or IPPD (4010NA) offering necessary short-term safety activate in the early stage and anti-aging agent DTPD will effect protective function for long.
    4. 3. Since both sides of benzene ring of Vestox™ DTPD molecular structure cause one or two solubilizing gene, its solubility greatly increases in rubber and crocking is low. Large dosage is allowable in glue stuff.
    5. 4.Due to lowl alkalinity, Vestox™ DTPD has little effect to vulcanization and scorching, especially since it is with strongest metal poison resistance para phenylene diamine of anti-aging agent group in long effective time, it is specially suitable to load tyre, off-highway tyre and kinds of radial tyres and bias belted tyres requiring hard conditions.
    6. 5. Vestox™ DTPD can also completely overcome the default of red tyre appearance of antioxidant 6PPD (4020) or IPPD (4010NA).
