74-31-7 N,N-Diphenyl-p-phenylenediamine Rubber Antioxidant DPPD C18H16N2

Rubber antioxidant DPPD, also known as N,N-Diphenyl-p-phenylenediamine, is a general antioxidant used in natural rubber and latex. It has excellent resistance to flexural cracking and has excellent protection against heat, oxygen, ozone, and photoaging, especially copper and manganese damage.

Antioxidant DPPD causes serious discoloration and pollution. It is often used in the manufacture of tires and various industrial rubber products, as well as wires, cables and rubber materials in contact with steel. Because this product has low solubility in rubber and is easy to bloom, the general dosage when used alone is 0.2~1.0 parts.

This product is also used as a heat-resistant anti-aging agent for ABS, polyformaldehyde, polyamide engineering plastics, polyvinyl chloride and other plastics.
