The addition of antioxidants prevents polymer degradation during processing and prevents oxidation of the finished product during use. Antistatic additives are used in many packaging grades to reduce the adhesion of bottles or packaging to dust and dirt. Specific applications require special additive formulations, such as copper inhibitors associated with wire and cable applications. Excellent weather resistance and resistance to UV (or sunlight) can be achieved by adding anti-UV additives. No added UV or carbon black PE, not recommended for continuous outdoor application. High grade carbon black pigments provide excellent UV resistance and are often used in outdoor applications such as wire, cable, tank layer or pipe.
