What is Antioxidant 168?
Antioxidant 168 is an organophosphate antioxidant of low volatility and high resistance to hydrolysis. It acts as a secondary antioxidant, primarily protecting polymers from degradation during high-temperature thermal processing.
In which applications is Antioxidant 168 commonly used?
It is widely used in polyolefins such as polyethylene (PE) and polypropylene (PP), polycarbonates (PC), polyesters, and engineering plastics to prevent color change and physical property degradation.
How does Antioxidant 168 exhibit synergistic effects?
When paired with primary hindered phenolic antioxidants (such as Antioxidant 1010 or 1076), it forms a highly effective stabilizer system, offering significantly enhanced thermal stability during polymer processing.
What is the standard packaging and storage condition for Antioxidant 168?
It is standardly packed in 25Kgs bags. It should be stored in a cool, dry, and well-ventilated warehouse. Keep away from direct sunlight, moisture, and high temperatures to prevent hydrolysis.
