great price rubber antioxidant dtpd
properties: soluble in gasoline, benzene, acetone etc. insoluble in water.it will become black on exposure to air, but there is no effect on its properties. due to low melting point, it should be stored away from high temperature. application: an antioxidant used for rubber products with high efficiency, low poison and low.
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.
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.

antioxidant 4020 (6ppd)
product name: antioxidant 4020(6ppd) chemical name: n-(1,3-dimethylbutyl)-n’-phenyl-p- phenylenediamine.it has powerful antiozonant and antioxidant properties with excellent high temperature , fatigue and flex resistance to rubber polymers. and will.
environmental fate of tire-rubber related pollutants 6ppd and 6ppd-q: a,abstract. 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.
rubber antioxidant 6ppd 4020 793-24-8 manufacturer
rubber antioxidant 6ppd is a high-performance antioxidant that is designed to protect rubber products from oxidative degradation caused by environmental factors such as heat, oxygen, and ozone. it is a dark purple-brown solid that is soluble in organic solvents and has a melting point of approximately 46-50°c.
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.
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- Do Antioxidants improve the performance of rubber?
- Conclusions and Future Perspectives Antioxidants are widely used to improve the performance of rubber, and their production, especially 6PPD, is annually maintained at a high level .
- Are rubber antioxidants toxic?
- (2) The toxic effects of rubber antioxidants and their TPs may be evaluated via computational toxicology combined with traditional toxicological methods, including studies of short-term and sub-lethal exposure effects, the potential for mortality, mechanism of effect, and interaction with environmental variables.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
