(pdf) 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...
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.

our sub-segments include cement additives, pressure sensitive, hot melt, flooring and contact adhesives. the portfolio includes antioxidants, hydrocarbons resin, monomers, rosin esters, rubber elastomers, water based dispersions and waxes (micro, paraffin, polyethylene).
accelerators and antioxidants in the rubber industry,preventing the bacterial oxidation of rubber. With its exceptional oxidation resistance, Rubber Antioxidant TMQ is ideal for prolonging the lifespan of rubber products such as tires, rubber tubes, and cables. It protects against cracking, breaking, and becoming brittle, even in high-temperature and high-humidity conditions.
synthesis and properties of a novel reactive and low
in this work, a new kind of accelerator modified antioxidant denoted as btc was synthesized successfully through a thiol-ene click reaction between accelerator 2-mercaptobenzothiazole (mbt) and antioxidant n-(4-anilino phenyl) maleic imide (mc).
rubber antioxidants and chemical 6ppd,amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.
recent progress in the rubber antioxidants Rubber Auxiliary Agent
in this review, we systematically review the recent progress of antioxidants for rubber. we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants.

- Can antioxidants prevent rubber aging?
- 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).
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- What is oxidative aging of rubber?
- Thermal oxidative aging is the most frequent type of rubber degradation. To delay or prevent this process, antioxidants can be added to rubber compounds during mixing. (9) Antiaging agents react primarily with the free radicals or hydrogen peroxide generated during rubber aging.
