Beschreibung
Zusammenfassung:The invention provides a composition comprising at least the following components: A) a first composition comprising a first ethylene/α-olefin block copolymer consisting of ethylene and C4-C8 α-olefin comonomer; and where the first composition has a density from 0.87 g/cc to 0.90 g/cc, and a melt index (I2) from 6.0 to 20.0 g/10 min; B) at least one filler that is capable of being excited by an alternating electromagnetic field at a frequency greater than, or equal to 10 MHz; C) at least one flame retardant selected from the group consisting of i) from 30.0 to 50.0 wt % of one or more non-halogen, inorganic flame retardant compounds, based on the weight of the composition; and ii) from 8.0 to 30.0 wt % of one or more halogen-containing flame retardant compounds, based on the weight of the composition; and D) at least one polar polymer.
