recent progress in the rubber antioxidants Rubber Auxiliary Agent,recent advances in the blooming/migration issues for rubber antioxidants. currently, many commonly used rubber antioxidants are low molecular weight derivatives of aromatic amines and phenols, and they are plagued with volatility, migration, and extractability issues.
N-Isopropyl-N'-phenyl-p-phenylenediamine (often abbreviated ippd) is an organic compound commonly used as an antiozonant in rubbers. like other p-phenylenediamine-based antiozonants it works by virtue of its low ionization energy, which allows it to react with ozone faster than ozone will react with rubber.

rubber antioxidant ippd, also known as n-isopropyl-n'-phenyl-p-phenylenediamine (cas 101-72-4), is a dark brown to dark purple granular or flake. it is primarily used as an antioxidant in rubber industry applications to improve the aging resistance of rubber products.
rubber antioxidants crossland chemicals,cas no. 101-72-4 performance: ippd is an outstanding antioxidant and antiozonant, which exhibits strong anti-ozone, anti-fatigue and anti-bending performance. it's oxidation resistance performance is better than that of quinolone and amine antioxidants.

- How often do people get exposed to IPPD during curing rubber?
- In a poorly reported human study, urine was collected twice daily (pre- and post-shift) over a 2 week period from 16 people occupationally exposed to IPPD during the curing of rubber (Scansetti et al, 1987). No information was provided as to the route, level or duration of exposure.
- Can IPPD be disposed of sludge from rubber production?
- There may be disposal of IPPD to land from rubber production; this should be as controlled waste. The octanol-water partition coefficient indicates that adsorption to sludge should occur, although the majority of the chemical would be hydrolysed.
- Is IPPD corrosive?
- The skin and eye irritation studies in animals and humans indicate that IPPD is not corrosive. In a maximisation test, groups of 20 guinea pigs were induced using an unstated number of intra-dermal injections of 0.5% IPPD followed 1 week later by a topical application of 1% IPPD (Herve-Bazin et al, 1977).
- Is IPPD toxicity to soil dwelling organisms?
- There is no information on toxicity to soil dwelling organisms for the hydrolysis products of IPPD, although this is not expected to be a principle exposure route. The rapid hydrolysis of IPPD must be considered when reviewing the available aquatic test results.
