1,4-Benzenediamine N,N'-mixed phenyl and tolyl derivs 68953-84-4

Antioxidant DTPD (N,N'-dimethylphenyl p-phenylenediamine) is a p-phenylenediamine rubber antioxidant, mainly used to enhance the anti-aging properties of rubber products. ‌

Chemical properties
Its chemical formula is C₂₀H₂₀N₂, and its molecular structure contains N,N'-dimethylphenyl p-phenylenediamine groups. It is a brown-gray granular solid with an initial melting point range of 90-100°C. This substance is a non-hazardous chemical and meets environmental protection requirements. ‌

Functions and applications
It is mainly used for anti-aging of truck tires, off-road tires and bias tires, especially for anti-ozone protection of sidewall rubber and tread rubber. Its long-term protective effect is significant. When used in combination with antioxidant 6PPD or 4010NA, it can form a synergistic effect and increase the service life of the tire.
