Improved lead-free insulation compositions containing metallocene polymers

摘要

Disclosed is a lead-free insulation composition for electric cable comprising: (a) a base polymer comprising 20% to 99% by weight of a metallocene polymer and 1% to 80% by weight of a non-metallocene polymer; (b) a filler; and (c) an additive comprising (i) an antioxidant, and (ii) a hindered amine light stabilizer; wherein no ingredients containing more than a trace amount of lead have been added to said composition.
