摘要： A polymeric composition includes 10 wt % to 80 wt % of a silane-grafted ethylene polymer based on a total weight of the polymeric composition. The silane-grafted ethylene polymer has a silane content of 0.40 mol % to 1.50 mol % based on a total moles of the silane-grafted ethylene polymer and the ethylene polymer used to make the silane-grafted ethylene polymer has a polar comonomer content of less than 15 wt % based on a total weight of the ethylene polymer. The polymeric composition also includes 10 wt % to 80 wt % of a flame-retardant filler based on a total weight of the polymeric composition.
