This is a new type of p-phenylenediamine antioxidant, because the two aryl substituting groups are so large that it has low volatility, slow oxidation rate and long effective time. Used with the similar antioxidant like 4010A or 4020 it can make up for the antioxidant which is well efficient in early time but insufficient in the later time. At the same time, its anti-metal toxicity is better than 4010NA and 4020, and it is suitable for heavy loading tyre, cross-country tyre and car tyre under harsh conditions.

It is a special effective antiozonant for chloroprene rubber. Its capability to resist ozone, flexibility and cracking is similar to antioxidant 4010 NA and 4020, but its irritation to skin is little, and can provide a long-term protection.

The product can prevent color change (to red) of tyres using antioxidant 4010NA/4020.
