Product Overview

6PPD (DMBPPD, 4020) is a widely used amine-type rubber antioxidant and antiozonant. It is designed to improve the durability of rubber products by protecting them against cracking, flex fatigue, heat aging and ozone attack during processing and service life.

6PPD is a gray black solid. Soluble in benzene, acetone, toluene, etc., insoluble in water.

This product is a pollution antioxidant. In addition to its good antioxidant performance, it also has the functions of resisting ozone, resisting bending and cracking, and inhibiting harmful metals such as copper and manganese. Its performance is similar to the antioxidant 4010NA, but its toxicity and skin irritation are less than 4010NA, and its solubility in water is better than 4010NA (washing loss rate: 4010NA is 50%, while 4020 is only 15-20%) .

Performance Benefits

Helps prevent ozone cracking and thermal aging.
Improves storage stability and service life of rubber products.
Supports better protection during dynamic flexing and outdoor exposure.
Widely accepted in tire and technical rubber formulations.

Typical Applications

Tires and tire components
Rubber hoses and belts
Industrial rubber goods
Seals, gaskets and vibration parts
Latex and elastomer systems requiring strong antiozonant protection

It can be widely used in the preparation of tires, tapes and many other industrial rubber products, with a general dosage of 0.5-1.5%. This product is not suitable for making light-colored products due to serious pollution. Anti-aging agent 4020 is one of the main varieties of p-phenylenediamine antioxidants. Para-phenylenediamine antioxidants are currently the main high-quality varieties commonly used in the rubber industry at home and abroad, and are also the development direction of antioxidants in the future.
