Product Name：Anti-aging agent
CAS ：793-24-8
Anti-aging agent refers to substances that can delay the aging of polymer chemistry. Most can inhibit the oxidation, some can inhibit the effect of heat or light, thus extending the service life of the product. Generally divided into natural antioxidants, physical antioxidants and chemical antioxidants. According to its role can be divided into antioxidants, anti-ozonants and copper inhibitors, or into discoloration and non-discoloration, staining and non-staining, heat-resistant or flexural aging, as well as to prevent cracking and other aging antioxidants. Natural antioxidants are found in natural rubber. Other antioxidants are widely used in various rubber products.
It is mainly used in natural rubber and synthetic rubber, and is a polluting antioxidant among p-phenylenediamine antioxidants, which has good antioxidant efficiency and excellent protection against ozone cracking and flexural fatigue. Its performance is similar to that of antioxidant 4010NA, but its toxicity and skin irritation is less than 4010NA, and its solubility characteristics in water are better than 4010NA. It is widely used in the preparation of industrial rubber products such as aircraft, bicycle, automobile tires, wire and cable, and adhesive tape, etc. The general dosage is 0.5-1.5%. The product is not suitable for the production of light-colored products because of more serious pollution. P-phenylenediamine antioxidant is the main excellent species commonly used in the rubber industry at home and abroad, but also the future direction of antioxidant development.
