74-31-7 - Application:

Antioxidant H (Antioxidant DPPD) (CAS: 74-31-7) is used as an antioxidant in the rubber industry.
Antioxidant H (DPPD) is a strong antioxidant properties of amine antioxidants, like general amine antioxidants, it has strong protective performance to heat, oxygen, light aging factors. used in natural butadiene-styrene, Butyronitrile, cis-butyl, butyl, polyisoprene and other rubber, latex, it can have good resistance to multiple flexing and crack resistance. Improve the tensile strength, enhance the thermal oxygen, ozone and copper wall iron manganese and other harmful metal protection, no effect on sulfide.
The combination of Antioxidant H and Antioxidant D can solve various aging problems of dark rubber products. In addition, it is also used as a thermal oxygen stabilizer for polyethylene, polypropylene, polyamide and polyformaldehyde engineering plastics to improve the weather resistance of products.
Antioxidant H (DPPD) is widely used in various kinds of industrial rubber products, especially suitable for all kinds of automobile tires, motorcycle tires, moped, tire tread compound. Antioxidant H (DPPD) is often used in all kinds of belt, transmission belt, conveyor belt, etc., as well as a variety of rubber pad and wire and cable. It is also used for daily necessities such as soles.
Dosage of Antioxidant H (DPPD): Reference dosage: 0.2%~0.3%. The effect and solubility of different varieties of antioxidants in natural rubber are very different, rubber products manufacturers use antioxidants to consider the specific use of products and performance needs, but also to avoid the occurrence of excessive dosage caused by frost spraying problems.
