? UV-light promotes free radical oxidation of the rubber surface which results in the formation of a film of oxidized rubber on the surface of the product (called as Frosting) . ? Heat & Humidity accelerate this process. ? Light colored rubber products are more prone to UV-light attack than the black colored products (as

Rubber Antioxidants and Their Transformation Products: Environmental

Natural antioxidants are only found in NR, such as amino acids, tocotrienol, and betaines , whereas physical and chemical antioxidants are widely used in various synthetic rubber products. The rubber-aging process comprises three stages: initiation, reaction, and termination [ 15 , 16 ], and the physical antioxidants are usually used to address the initiation stage of rubber aging.

Recent progress in the rubber antioxidants: A review

This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers. The oxidative degradation of rubber proceeds by a free-radical chain reaction mechanism [1]. As shown in Fig. 1a, rubber aging processes have three distinct phases: (i) Initiation, (ii) Propagation, and.

Insight into the anti-aging mechanisms of natural phenolic antioxidants

In this study, we chose natural rubber (NR) as a matrix and provided a screening strategy based on diverse natural phenolic antioxidants to evaluate their ability in protecting NR composites. Thymol, a-tocopherol, and lipid-soluble epigallocatechin gallate (lsEGCG) were chosen from 18 natural phenolic antioxidants as potential alternative
