6ppd rubber antioxidant: characteristics, applications, combinations,6ppd is an organic compound belonging to the p-phenylenediamine class of antioxidants. it is a dark purple solid with a slight odor. chemically, it consists of n- (1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine molecules. 6ppd is known for its solubility in rubber and compatibility with various types of rubber. 2.
computational studies of rubber ozonation explain the effectiveness of
this and other pressures have led the development of highly effective rubber additives that protect rubber from degradation during manufacture and use, most notably p-phenylenediamines (ppds). (3,4) among these, 6ppd ( n -(1,3-dimethylbutyl)- n ′-phenyl- p-phenylenediamine) in particular has gained ubiquity in the tire industry and is included at 0.5–1.5 wt % in standard formulations.

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.

- What are the different types of antioxidants used in rubber industry?
- The most widespread used antioxidants are phenolic and amine-based synthetic antioxidants and 2,2,4-trimethyl-1,2-dihydroquinoline in rubber industry. However, synthetic antioxidants cause some environmental problems during their production and tend to be replaced by natural alternatives.
- What is oxidative aging of natural rubber?
- Oxidative aging of natural rubber (NR) leads to the deterioration in the physical and mechanical properties. Using various antioxidants during compounding is a common way to improve the aging resistance of NR.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
