the data confirm that when tire rubber antioxidants react with ozone, as intended, they form and release various tps to surrounding environments. keywords: antioxidants, 6ppd-quinone, ozone, yield, toxic chemicals, roadway runoff, microplastics introduction tire tread wear particles (twps) are increasingly recognized
transformation products of tire rubber antioxidant 6ppd in,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppdq), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation. to address these data gaps, gas-phase ozonation of 6ppd was.

ples.28−32 6ppd is ubiquitously used in tire rubbers as an antioxidant at 0.4−2% by weight,33 where it is designed to quickly react with ground-level o 3 to protect rubber elastomers.34,35 such reactions inevitably form other trans-formation products (tps) beyond 6ppdq during the tire rubber lifetime.21,34 for example, early studies on the
6ppd rubber antioxidant: characteristics, applications,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.

environmental fate of tire-rubber related pollutants 6ppd and,to enhance tire durability, the antioxidant n- (1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is used in rubber, but it converts into the toxic 6ppd quinone (6ppd-q) when exposed to oxidants like ozone (o 3), causing ecological concerns. this review synthesizes the existing data to assess the transformation, bioavailability, and.
rubber antioxidants: tmq, 6ppd, ippd chemical products
6ppd, or n-1,3-dimethylbutyl-n’-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. it provides protection against degradation caused by heat, oxygen, and flex-cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending the service life of rubber products.
screening p-phenylenediamine antioxidants, their,recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized. here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers.
- Are p phenylenediamine (PPD) antioxidants in recycled tire rubber products toxic?
- Recently, roadway releases of N, N ′-substituted p -phenylenediamine (PPD) antioxidants and their transformation products (TPs) received significant attention due to the highly toxic 6PPD-quinone. However, the occurrence of PPDs and TPs in recycled tire rubber products remains uncharacterized.
- Is 6PPD in tires a priority product?
- DTSC designates 6PPD in tires as a Priority Product and USTMA expands its consortium to 32 tire manufacturers from around the world to prepare a Preliminary (Stage 1) Alternatives Analysis (AA) to identify and evaluate potential alternatives to 6PPD in tires. Individual consortium members submitted the report to DTSC to meet compliance deadline.
- Should 6PPD be a priority product?
- USTMA mobilizes a consortium of 16 tire manufacturers to conduct an alternatives analysis for 6PPDin tires after a decision by DTSC to act on USTMA’s recommendation to list 6PPD in tires as a Priority Product under the state’s Safer Consumer Products (SCP) program.
- Which industrial rubber additives have higher chemical concentrations?
- Furthermore, we quantified 15 other industrial rubber additives (including bonding agents, vulcanization accelerators, benzotriazole and benzothiazole derivatives, and diphenylamine antioxidants), observing that PPD-derived chemical concentrations were 0.5–6 times higher than these often-studied additives.
