Applications of N-Phenyl-N-cyclohexyl-p-phenylenediamine丨CAS 101-87-1
1. Rubber Industry – Antioxidant and Antiozonant
● Primary use: As a high-performance antioxidant and antiozonant in the rubber and tire industry
● Protects natural rubber (NR) and synthetic rubbers (e.g., SBR, BR, NBR) against:
o Oxidation
o Ozone cracking
o Heat degradation
● Commonly added to:
o Tires (especially sidewalls)
o Conveyor belts
o Hoses
o Seals and gaskets
o Other industrial rubber goods exposed to harsh environments
2. Protective Additive in Harsh Environments
● Provides long-lasting protection against atmospheric degradation, especially in outdoor or ozone-rich environments
● Common in automotive and aerospace rubber applications due to its durability
3. Plastics and Polymer Additive
● Occasionally used in plastics to stabilize against oxidative degradation, especially in blended or filled polymers
Benefits
1. Superior Ozone and Oxidation Protection
● N-Phenyl-N-cyclohexyl-p-phenylenediamine丨CAS 101-87-1 effectively scavenges free radicals and absorbs ozone, which prevents chain scission and cracking in elastomers
● Maintains mechanical integrity and elasticity of rubber materials over time
2. Extended Product Lifespan
● Greatly enhances the durability and service life of rubber-based products in dynamic and static conditions
● Especially valuable in tires, where cracking from ozone and UV exposure is a critical failure mode
3. Good Compatibility with Various Rubber Compounds
● Compatible with both polar and non-polar rubbers
● Does not significantly interfere with vulcanization or curing processes
4. Thermal Stability
● Resists thermal degradation at high processing and operating temperatures, ensuring long-term efficacy
Conclusion
N-Phenyl-N-cyclohexyl-p-phenylenediamine丨CAS 101-87-1 is a critical compound in the rubber and elastomer industry, valued for its exceptional antioxidant and antiozonant properties. It plays a pivotal role in preventing degradation of rubber components exposed to ozone, UV light, and heat, thereby prolonging the life of tires, belts, seals, and industrial rubber goods. Its chemical stability, broad compatibility, and protective action make it a preferred additive in demanding applications across automotive, industrial, and transportation sectors.
