Product Info
Characteristic
Gray-black solid. Soluble in benzene, acetone, toluene, etc., insoluble in water.
Application:
The product is a polluting antioxidant, in addition to having a good antioxidant effect, but also anti-ozone, anti-flexion cracking and inhibition of copper, manganese and other harmful metals. Its performance is similar to that of antioxidant 4010NA, but its toxicity and skin irritation are smaller than 4010NA, and its solubility in water is better than 4010NA (washing loss rate: 4010NA is 50%, while 4020 is only 15-20%). 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%. The product is not suitable for making light-colored products due to serious pollution. Antioxidant 4020 is one of the main varieties of p-phenylenediamine antioxidant. P-phenylenediamine antioxidant is the main excellent variety commonly used in rubber industry at home and abroad, and also the development direction of antioxidant in the future.
It is an anti ozone agent and antioxidant for natural rubber and synthetic rubber, and has excellent protective effect on ozone cracking and flexure fatigue
