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.

摘要： The process disclosed includes an extruder under extrusion conditions at a temperature from 50° C. to 250° C., and a polymer composition. The polymer composition includes (A) greater than or equal to 5 wt % of a silane functionalized olefin-based polymer with first melting temperature, Tm1, (B) optionally, a nonsilane functionalized polyolefin, with second melting temperature, Tm2, (C) a highly effective silanol condensation catalyst (HEC), (D) a permeability modifier, and (E) optionally, a scorch inhibitor. The process includes introducing a physical blowing agent into the polymer composition to form a foamable composition. The foamable composition is cooled to a foaming temperature from 10° C. less than to 10° C. greater than Tm1. The foamable composition from an extruder exit die to form a foam composition. The foam composition is moisture cured to form a crosslinked foam composition having a density from 0.010 g/cc to 0.200 g/cc, and a gel content from 5% to 100%.
