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: Flooding compounds for telecommunications cables. Such flooding compounds contain a polymeric filler and a branched olefinic fluid. The branched olefinic fluid has an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. Additionally, the average number of carbons per molecule in the branched olefinic fluid is from 25 to 200.
