new evidence of rubber-derived quinones in water, air, and soil,five p-phenylenediamine-derived quinones have been identified to be pervasive in roadside soil, runoff water, and air particles, while their health risks remain elusive. research findings demonstrate the coexistence of five quinones from globally ubiquitous p-phenylenediamine antioxidants in urban runoff, roadside soils, and air particles. 1.
6ppd (6ppd or n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a widely used rubber antioxidant that plays a vital role in the production of rubber products. this article aims to provide an overview of 6ppd, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. what is 6ppd? 6ppd.
rubber antioxidants: tmq, 6ppd, ippd chemical products
antioxidants are substances that are used in rubber and plastic industries to prevent oxidation and decay of polymer materials. tmq, also known as polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, is a widely used rubber antioxidant. it provides excellent protection.
recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
improvements of lanthanum complex on the thermal-oxidative stability of
mixed antioxidants composed of antioxidant ippd and novel rare earth lanthanum complex were used as an additive to prepare natural rubber (nr) samples. the variations of macro-properties, surface characterizations, and internal groups were investigated by mechanical testing, x-ray photoelectron spectroscopy, and thermogravimetric analysis coupled with fourier transform infrared spectroscopy.

- 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.
- 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.
- 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.
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
