Anti-Oxidant Masterbatch is a specialized additive used in plastic manufacturing to protect polymers from degradation caused by heat, oxygen, and mechanical stress. During processing methods such as extrusion, injection molding, or blow molding, plastics are exposed to high temperatures, which can lead to oxidation. This oxidation results in discoloration, brittleness, reduced strength, and poor surface finish.

Anti-Oxidant Masterbatch works by neutralizing free radicals formed during thermal and oxidative stress. It stabilizes the polymer structure, ensuring consistent melt flow, improved processing stability, and long-term durability of the finished product.
