Antioxidants play a crucial role in the plastic industry, where they are utilized to prevent the oxidative degradation of polymers. This degradation, caused by the reaction with oxygen in the environment, can lead to a loss of physical and mechanical properties of the wellt polymer products. Hence, understanding the role of antioxidants in maintaining the stability and extending the lifespan of plastic products is vital for both manufacturers and consumers. This article aims to delve into the technical aspects of this topic while providing an informative and professional perspective.
Primary antioxidants, also referred to as radical scavengers, function by reacting with and neutralizing free radicals in the polymer matrix, thus preventing chain reactions that lead to significant degradation. On the other hand, secondary antioxidants decompose peroxides and disrupt auto-oxidation cycles, further enhancing polymer stability. Both types play a crucial role in maintaining the integrity and extending the lifespan of plastic goods.
