Stabilizers are a type of additive. Generally speaking, there are two types of stabilizers.
UV stabilizersprotect a film from degradation caused by ultraviolet radiation, which is particularly important when products are exposed to the sun during transport or storage. These additives help preserve the structure of the plastic and extend the film's service life.
Antioxidants are stabilizers that prevent the material from oxidizing, which in turn can lead to a deterioration in its mechanical properties. Examples of such effects include brittleness and color changes. The use of stabilizers such as antioxidants helps prevent these issues.
