Sunlight-Induced Transformation of Tire Rubber Antioxidant N‑(1,3-Dimethylbutyl)‑N′‑phenyl‑p‑phenylenediamine (6PPD) to 6PPD-Quinone in Water

, 2023
The huge consumption of the tire rubber antioxidant N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) has resulted in pervasive contamination in aquatic environments.

Structure and Toxicity Characterization of Alkyl Hydroxylated Metabolites of 6PPD-Q

Environmental Science & Technology
Distinct from other nontoxic PPD quinones, 6PPD-Q was recently discovered to be regioselectively metabolized to alkyl hydroxylated metabolites (alkyl-OH-6PPD-Q) in rainbow trout. It remains unknown whether the unique alkyl-OH-6PPD-Q might contribute to the toxicity of 6PPD-Q.

Occurrence and risks of 23 tire additives and their transformation products in an urban water system

Environment International, 2023
Tire wear particles (TWPs) enter road surface with the friction between tires and road surfaces. Under the volatilization, leaching, and transformation action on TWPs by sunlight and rain, tire additives are released into urban water systems, such as ...

Analysis of 6PPD-Q in finfish, shellfish, and marine mammal tissues

Chemosphere
6PPD-quinone (6PPD-Q), a transformation product of tire rubber anti-oxidant 6PPD, has been identified as the primary causal toxicant for the urban runoff mortality syndrome observed in coho salmon (Oncorhynchus kisutch) in the Pacific Northwest, USA. Several other fish species are also vulnerable to 6PPD-Q.

Synergistic Network Formation in SBR/ANF Composites: GMA Bridging and Electron‐Beam Crosslinking for Enhanced Strength and Damping Control

Polymer Engineering &Science, Volume 66, Issue 8, Page 5819-5830, August 2026.
Styrene‐butadiene rubber/aramid nanofiber composites interfacially reinforced with glycidyl methacrylate via electron beam irradiation. ABSTRACT Styrene‐butadiene rubber (SBR) is widely used in tire and damping applications, yet its reinforcement with polar nanofillers is often limited by weak interfacial adhesion in nonpolar matrices.

The Effects of Microplastics and Additives on Ecosystem Function, Structure, and Signaling

Global Change Biology, Volume 32, Issue 8, August 2026.
Microplastics disrupt ecosystem signaling through olfactory traps, altering predator–prey signaling and disrupting microbial communication and quorum sensing. ABSTRACT Microplastics (MPs) and their associated chemical additives are pervasive contaminants whose ecological impacts extend beyond organismal toxicity to fundamentally alter ecosystem ...

6PPD-Q exposure promotes hepatocellular carcinoma progression and confers resistance to ferroptosis

Ecotoxicology and Environmental Safety
Tire antioxidant degradation product N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine quinone (6PPD-Q), an emerging environmental pollutant, has been suggested to influence tumor-related biological processes; however, its role in HCC remains unclear.

A Novel Framework for Understanding Multiaxial Fatigue of SBR Through Monitored Tension‐Torsion Tests

Strain, Volume 62, Issue 4, August 2026.
A new methodology shows that current multiaxiall fatigue criteria are not sufficient. ABSTRACT In the present work, mappings of two invariants of the true strain tensor, K2$$ {K}_2 $$ that measures the magnitude of the distortion and K3$$ {K}_3 $$ that quantifies the mode of distortion, are used to investigate the multiaxial fatigue of AE2 and AE42 ...

Latex Serum‐Derived Supramolecular Networks Enable Toughening of Natural Rubber

Macromolecular Rapid Communications, Volume 47, Issue 10, 19 May 2026.
Latex‐serum addition enhances strain‐induced crystallization (SIC) toughening in natural rubber, increasing tearing strength and extending the SIC activation window. Supramolecular networks form via bifurcated hydrogen bonding between polyol components (e.g., quebrachitol) and end‐functionalized polyisoprene chains, serving as effective crystallization
