occurrence and oxidation kinetics of antioxidant p,the concentrations of all antioxidants in rubber powder decreased 50% within 4 days under natural aging, much faster than that in particles, suggesting the size effect on oxidation. different ppds had distinct oxidation degrees under both field and simulated experiments.
various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
rubber antioxidants and their transformation products
in this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their tps in the environment, emphasizing their influence on the ozone oxidative degradation.
transformation products of tire rubber antioxidant 6ppd for sale,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
synthesis and properties of a novel reactive and low
the addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. however, antioxidant migration can cause environmental pollution. to address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (gma) and p-aminodiphenylamine (ppda). the

effectiveness of different kinds of antioxidants in resin
the effectiveness of several antioxidants belonging to different chemical classes such as p-phenylene diamine (antioxidant 4010na), secondary amine (antioxidant 445), quinoline (antioxidant rd), and phenolic (bht, 1010, 2246) on the performance of a resin-cured biir vulcanizate was investigated.

- What is rubber antioxidant TMQ / Rd?
- In the realm of rubber manufacturing, the utilization of effective rubber additives is crucial to ensure superior product quality and longevity. One such essential rubber additive is the Antioxidant TMQ, also known as RD.
- Do antioxidants and their TPS increase environmental risk awareness of rubber products?
- To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
- Can polymerized TMQ reduce rubber oxidation?
- The addition of polymerizable antioxidants is one of the most preferable methods to overcome rubber oxidation [14, 15]. One of the mostly used antioxidants is polymerized TMQ. It is a secondary amine and can strongly inhibit the oxidation reactions of rubber [16, 17, 18].
- Is polymerized TMQ an antioxidant?
- One of the mostly used antioxidants is polymerized TMQ. It is a secondary amine and can strongly inhibit the oxidation reactions of rubber [16, 17, 18]. Zidan et al. prepared galloyl hydrazide and used it as antioxidant for natural rubber (NR).
