IMPROVED INSULATION COMPOSITIONS CONTAINING METALLOCENE POLYMERS

摘要

Novel antioxidant systems for metallocene based filled cable insulation are disclosed. These antioxidant systems provide excellent protection against thermal degradation, better cure state and reduced dissipation factor after prolonged heat exposure. The antioxidants consist of mixtures of hindered amine light stabilizers or sterically hindered amine light stabilizers and amine antioxidants.
