IRGANOX® antioxidants

Reliable antioxidants to prevent oxidation of polymers from heat exposure that extends from production and application – e.g. processing and curing or baking at high temperatures – to service life. 

The IRGANOX lineup is made up of sterically hindered phenols and thioethers as well as blends of different AO technologies.

Key features & benefits

  • Hindered phenol AO 
  • Activity over broad temperature range (RT to melt) 
  • Improve long-term stability 
  • Non-regenerative mechanism and consumption during reaction 
  • Thioether AO 
  • Rate of ROOH decomposition increases with temprature 
  • Designed to protect against high temperature ageing
