rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.
rubber antioxidant dtpd( 3100) identification: chemical name: 1,4-benzenediamine n,n'-mixed phenyl and tolyl derives synonym: (n,n'-ditolyi-p-phenyl diamine mixed);dtpd; n,n'-bis(methylphenyl)-1,4-benzenediamine cas no.: 68953-84-4 properties: antioxidant dtpd is antioxidant of para-phenylene diamine ursol, as antiozonant of neoprene; also widely used in various rubber products.
best selling rubber antioxidants tmq particles
china is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. the production of rubber antioxidants in china ranged from 365,000 to 378,000 tons during 2016–2020, showing a
rubber antioxidant dtpd (3100) supplier,its performance of anti-ozone, anti-scratch and anti-cracking is far better than antioxidant a and d. dtpd has good long-term performance especially used with the antioxidant 4020 or 4010na 1:1. its greatly increased solubility in rubber and the much lower blooming allow a greater using amount. it has little influence on vulcanization and scorch.
screening p-phenylenediamine antioxidants, their transformation
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.

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.
- Do antioxidants and their TPS increase environmental risk awareness of rubber products?
- To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
- What are amine antioxidants in rubber?
- Amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. Typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p -phenylenediamine, and aldehyde-amine condensation product antioxidants .
- Which rubber antioxidants are used in China?
- 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.
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
