Abstract
Novel additive systems for lead-free filled cable insulation are disclosed. These systems provide improved electrical and mechanical properties. The base polymer may be metallocene based, non metallocene based or combinations thereof. The additives may contain one or more hindered amine light stabilizers, mercapto compounds, and optionally, amine antioxidants.
