What is the best antioxidant for chloprene rubber?

Antioxidant DTPD (3100), which can be classified in p-phenlene antioxidant groups, is excellent antioxidant to chloprene rubber. It is the effective antioxidant used in the tire industry and also widely used for rubber products. 1.

What is the chemical name for chloprene rubber?

Chemical Name: N,N'-ditoly-p-phene diamine mixed. Antioxidant DTPD (3100), which can be classified in p-phenlene antioxidant groups, is excellent antioxidant to chloprene rubber. It is the effective antioxidant used in the tire industry and also widely used for rubber products.

Are rubber antioxidants a rational design?

The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .

How does rubber antioxidant work?

To prolong the service life of rubber composites by retarding their aging processes, rubber antioxidant initially relies on the use of a coating, such as paraffin, and coal tar, to physically isolate oxygen, but this protective layer would quickly lose the utility due to wear.

What are the future trends of rubber antioxidants?

The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.

Why do we need antioxidants for rubber composites?

Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
