High-Performance Phosphite Processing Stabilizer
Synergistic Antioxidant for Plastics – Prevent Thermal Degradation & Extend Product Lifespan
Antioxidant 168 (CAS: 31570-04-4) is a hydrolytically stable phosphite processing stabilizer, widely used as a secondary antioxidant in combination with primary antioxidants (e.g., Irganox 1010). It effectively prevents hermos-oxidative degradation during plastic processing (e.g., extrusion, injection molding) and enhances long-term durability of finished products.
Synergistic Effect: Boosts performance when paired with phenolic antioxidants (e.g., Irganox 1010).
Hydrolysis-Resistant: Superior stability in humid environments vs. traditional phosphites.
Broad Compatibility: Works with PP, PE, ABS, PA, PET, and engineering plastics.
Regulatory Compliance: Meets FDA, EU 10/2011 (food contact), RoHS, and REACH standards.
