Advanced Color Protection
Effectively prevents yellowing and discoloration during high-temperature processing and extended residence times.
Primary Applications
  • Nylon drying process yellowing prevention below 150°C
  • Multiple screw passes and injection molding processes
  • Large part injection molding with extended cylinder residence times
  • High-temperature engineering plastics processing above 280°C
Polymer Compatibility
Engineering Plastics: Nylon, High-temperature nylon, PC, PBT, Polyester, Polyether
Standard Plastics: PP, PVC, PS, POM, ABS, PMMA, HDPE, LLDPE
Performance Advantages
  • Excellent stability in air and polymer matrices
  • Superior protection against thermal degradation during processing
  • Maintains color and torque stability in PC processing
  • Controls color and melt index in multiple LLDPE extrusions
  • Complies with FDA and EU-SCF certification standards
Mechanism of Action
As a secondary antioxidant, Antioxidant 9228 quenches hydrogen peroxide during autoxidation, preventing polymer degradation and discoloration. Its unique mechanism transforms dark intermediates from hindered phenolic antioxidants into lower chroma forms.
