Introduction

Plastics are vulnerable to thermo oxidative degradation during processing and usage, often due to elevated temperatures, high shear rates, or exposure to light and oxygen. This degradation process can lead to several undesirable consequences, including loss of strength, loss in elongation, surface roughness, color fading or discoloration and much more. Oxidation, the underlying mechanism behind thermo oxidative degradation, involves a chain reaction process mediated by free radical and hydroperoxide intermediates. Antioxidants play a crucial role in mitigating this degradation by decomposing free radicals through chemical reactions.

Features

• Effective Protection: Antioxidant masterbatches offer effective protection against thermo oxidative degradation in plastic materials, safeguarding them from the detrimental effects of heat, light, and oxygen exposure.
• Enhanced Stability: By inhibiting oxidation reactions, these masterbatches help maintain the stability and integrity of plastic products.
• Prevention of Strength Loss: Antioxidant masterbatches help prevent loss of strength in plastic materials.
• Maintained Flexibility: These masterbatches aid in preserving the flexibility and elongation properties of plastics, preventing brittleness and maintaining their ability to withstand mechanical stresses.
• Surface Protection: Antioxidant masterbatches contribute to maintaining the smoothness and glossiness of plastic surfaces, minimizing surface roughness and preserving aesthetic appeal.
