- Due to the presence of one or two solubilizing genes on the benzene rings on both sides of the molecular structure of anti-aging agent D'TPD, its solubility in rubber is greatly increased, and its spray properties are low, allowing for a larger amount to be used in the rubber compound.
- Due to its low alkalinity, antioxidant DTPD has little effect on vulcanization and scorching, especially due to its excellent resistance to metal toxicity in para phenylenediamine anti-aging agents, its protective effect lasts longer Especially suitable for heavy-duty tires, off-road tires, as well as various radial and diagonal tires with harsh operating conditions.
- The Antioxidant DTPD can completely change the defect of the appearance of tires turning red when using other anti-aging agents 4010NA and 4020.
