rubber additive rubber antioxidant 6ppd cas 793-24-8,6ppd provides powerful antiozonant and antioxidant properties with excellent high temperature, fatigue and flex resistance to rubber compounds. it gives efficient stabilization for a wide range of solution and emulsion polymers.
6ppd is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as nr, sbr and br; all of which are common in vehicle tires. although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.
antioxidant 6ppd chemical products for Rubber
6ppd is a strong antioxidant that is used as an antioxidant and antioxidation agent in rubber production. this substance has low toxicity and prevents polymer corrosion and increases the stability of the final product.
6ppd rubber antioxidant: characteristics, applications,6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.

abstract: 6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.

a tire industry perspective on 6ppd replacement: the challenge
to act like 6ppd, a drop-in substitute must: function as antiozonant and antioxidant to help prevent the degradation and cracking of rubber compounds (unsaturated elastomers) by protecting against ozone attack, oxidation, and heat aging.
6ppd rubber antioxidant new markers for sale,this study presents long-time scale data of ppds and n-(1,3-dimethylbutyl)-n′-phenyl- p-phenylenediamine quinone (6ppd-q) in pm2.5 and proposes the innovative use of ppds as new markers for vehicular emissions in the positive matrix factorization (pmf) source apportionment.

n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd), a typical p-phenylenediamine antioxidant, has been detected in human urine samples. however, the occurrence of other widely used ppds in human urine is still unclear.
from tread to watershed: how tire wear particle chemicals,the environmental ubiquity of tire and road wear particles (trwp) underscores the need to understand the occurrence, persistence, and environmental effects of tire-related chemicals in aquatic ecosystems. one such chemical is 6ppd-quinone (6ppd-q), a transformation product of the tire antioxidant 6ppd.
- Is 6ppd-q toxic?
- 6PPD-Q pose hazards to certain aquatic and terrestrial organisms at low concentrations. Toxic effects include neurobehavioral changes, reproductive dysfunction, and others. Toxic mechanisms include mitochondrial stress, DNA adducts, and lipid metabolism. 6PPD-Q in human samples highlight the need for further research on public health.
- What are the effects of 6PPD?
- 6PPD and its derivative 6PPD-Q have been found in widespread air, water, and soil. 6PPD-Q pose hazards to certain aquatic and terrestrial organisms at low concentrations. Toxic effects include neurobehavioral changes, reproductive dysfunction, and others. Toxic mechanisms include mitochondrial stress, DNA adducts, and lipid metabolism.
- Does 6PPD survive pyrolysis?
- The liquid pyrolysis oil product distribution and solid carbon black powder from the 1.3 mm and 0.6 mm particles are independent of the starting particle size (Fig. 1d); however, gas chromatography–mass spectrometry (GC–MS) of the oil product shows that 6PPD survives appreciably after pyrolysis (Supplementary Fig. 10).
