Irgafos® for Plastics

Irgafos® - Antioxidant and Process Stabilizer for Plastic Applications

Irgafos® comprises a range of secondary antioxidants for use in organic substrates such as plastics, synthetic fibers and elastomers. It ensures thermal protection and long-term durability as well as the integrity of polymer properties during processing.

Basket with Irgafos®

Irgafos® processing stabilizers and blends thereof are the market reference recommended to ensure processing stability (color and viscosity retention). They protect polymers from thermo-oxidative degradation during processing.
As a secondary antioxidant, they react with hydroperoxides formed by auto-oxidation of polymers, preventing process induced degradation and extending the performance of the primary antioxidant.
Irgafos® branded process stabilizers are available in all regions of the world offering the polymer value chain the required stabilization, manufacturing flexibility and supply security. BASF representatives are available globally to assist in identifying the appropriate Irgafos® process stabilizers for your application.


Thermal protection and processing stability for plastics

  • Excellent processing stability
  • Prevention of polymer discoloration due to degradation
  • Hydrolytically stable phosphite processing stabilizer
  • Synergistic performance when used in combination with primary antioxidants from the Irganox® range
