Recycled silica as a renewable and sustainable alternative to carbon black in natural rubber foams

Polymer International, Volume 72, Issue 12, Page 1104-1111, December 2023., 2023
Natural rubber foams were prepared by replacing petroleum‐based carbon black (CB) with recycled silica. The total filler concentration was fixed (40 phr), while the CB/silica ratio was changed. The results showed that recycled silica is a suitable alternative to CB producing superior mechanical and thermal properties compared to commercial silica ...

Recent applications of mass spectrometry in the analysis of transformation products of emerging contaminants in PM2.5

Analytical Science Advances, Volume 4, Issue 3-4, Page 49-59, May 2023., 2023
Abstract Ambient pollution correlated to fine particulate matter (PM2.5) is a worldwide environmental issue as it is highly associated with human health and eco‐environmental safety. A significant part regarding the toxicity of PM2.5 is attributed to its bonded contaminants. Appreciable efforts have been performed to study the occurrence, exposure, and

Acute Toxicity of 6PPD‐Quinone to Early Life Stage Juvenile Chinook (Oncorhynchus tshawytscha) and Coho (Oncorhynchus kisutch) Salmon

Environmental Toxicology and Chemistry, Volume 42, Issue 4, Page 815-822, April 2023., 2023
Abstract The breakdown product of the rubber tire antioxidant N‐(1,3‐dimethylbutyl)‐N'‐phenyl‐p‐phenylenediamine‐quinone (6PPD)‐6‐PPD‐quinone has been strongly implicated in toxic injury and death in coho salmon (Oncorhynchus kisutch) in urban waterways.

Acute Toxicity Testing of the Tire Rubber–Derived Chemical 6PPD‐quinone on Atlantic Salmon (Salmo salar) and Brown Trout (Salmo trutta)

Environmental Toxicology and Chemistry, Volume 41, Issue 12, Page 3041-3045, December 2022., 2022
Abstract Recent identification of 6PPD‐quinone as the chemical causing acute toxicity in coho salmon has led to substantial concern regarding the toxicity of this contaminant for other aquatic species. Environmental occurrence of 6PPD‐quinone is probably high, because it is an oxidation product of a common tire rubber additive. Research on 6PPD‐quinone

Low heat generation from organic zinc as a curing activator in rubber and rubber composites under large strain

Nano Select, Volume 3, Issue 5, Page 965-976, May 2022., 2022
ZnO is a conventional activator, but its excessive release may cause adverse effects to the human body and the environment. Using organic zinc to replace ZnO can not only reduce the amount of zinc but also disperse more effectively. The curing process are accelerated and the Payne effects are weakened when organic zincs are used as activators ...

Review of 6PPD-quinone environmental occurrence, fate, and toxicity in stormwater [PDF]

, 2023
The antioxidant N-(1,3-dimethylbutyl)-N?-phenyl-p-phenylenediamine (6PPD) is widely used to improve the durability of rubber. However, one of its transformation products, 6PPD-quinone (6PPD-Q), was recently found to be toxic.

Investigation of 6PPD-Quinone in Rubberized Asphalt Concrete Mixtures

, 2023
N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD)-quinone (6PPD-Q), a transformation byproduct of 6PPD used in tires as an antiozonant and antioxidant, was recently discovered as the chemical primarily responsible for the acute lethal toxicity of
