Antioxidant products can prevent polymers from undergoing chemical reactions or degradation during processing due to heat, shear stress, or exposure to other harsh processing environments. These reactions or degradation can lead to changes in the chemical composition or molecular weight of the product. Additionally, it can result in the deterioration of mechanical properties and affect the appearance, causing changes in the color of the polymer or a reduction in glossiness.
Antioxidants are products added to polymers during processing to protect the polymer's structure and prevent discoloration.
