GENERAL DESCRIPTION & EXTERNAL LINKS

IPPD is used as an antioxidant and antiozonant for natural and synthetic elastomers and as an antiflex agent for the protection against catalytic degradation by copper and other heavy metals. p-Phenylenediamine is used as a parent compound in vulcanization accelerators and in antioxidants for rubber industry. PPD is chosen because it imparts high temperature stability, high strength, and chemical and electrical resistance. Examples of the most widely used anitioxidants or antiozonants derived form p-phenylenediamine are N-isopropyl-N'-phenyl-p- phenylenediamine (IPPD, CAS # 101-72-4) , N-Cyclohexyl-N'-phenyl-p- phenylenediamine (CPPD, CAS #: 101-87-1), N,N'-Diphenyl-p-henylenediamine (DPPD, CAS # 74-31-7), and N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD, CAS #: 793-24-8). These derivatives are added to rubber products to retard degradation by oxidants and ozone.

Rubber articles when placed in service can fail prematurely due to ozone cracking. Ozone is present in the atmosphere at minute levels, about 50 parts per billion (ppb, commonly expressed as five parts per hundred Million). Ozone can be formed by the action of sunlight on smog particles, so the level generally increases in summertime to as high as 300 to 400 ppb, levels which can be harmful to humans as well as rubber parts. The rubber compounder has several methods available to protect the rubber part in service against ozone attack. These various antiozonant techniques will be reviewed in this article. But first, I would like to make a distinction between oxidation and ozone attack. Many people confuse the effects of oxygen and ozone. A common misperception of the neophyte is that once a rubber compound is well protected against oxidation, it will resist ozone as well. The incorrect converse is also heard; that the use of antiozonants eliminates the need for antioxidants.......

Polymer Stabilizers protect polymers from oxidative damage. They prevent discoloration and cross linking of polymers during progressing and ensure long term properties of the finished articles.
Phenolic Antioxidant(SONGNOX®) is a highly effective, non-discoloring stabilizer for organic substrates which are prone to oxidation, e.g. plastics, synthetic fibers, elastomers, waxes, oils and fats. 
Aminic Antioxidant maintain physical and surface properties with good color, excellent anti-scorch, good heat resistance. 
Phosphite Antioxidant(SONGNOX®) is used to protect organic polymers which are prone to oxidation, especially during progressing and color stabilizer......
