Introduction to Antioxidant 9228 CAS 154862-43-8
Antioxidant 9228 is a high-performance phosphite antioxidant with excellent hydrolysis resistance, anti-volatility, and processing thermal stability. This product can resist hydrolysis even when exposed to moisture for a long time, thereby maintaining particle shape and free flow characteristics.
When it is used in conjunction with light stabilizers, it maintains the color of the polymer and reduces its melt degradation in a synergistic manner. This product is widely used in special engineering plastics with higher processing temperatures and can effectively improve the processing thermal stability, anti-discoloration, and melt rheological stability of engineering plastics.
