Abstract:
1. A composition comprising: from about 12 wt % to about 50 wt % of a thermoplastic elastomer with a Shore hardness less than 50D as measured in accordance with ASTM D2240; from about 1 wt % to about 30 wt % of a polar olefin-based polymer; from about 48 wt % to about 75 wt % of a flame retardant comprising a metal hydrate and an oligomeric phosphate ester, wherein the weight ratio of metal hydrate to oligomeric phosphate ester is greater than 2.0-4.0:1; wherein the metal hydrate is present in an amount of 37 wt % to 45 wt %, based on the total weight of the composition, and the oligomeric phosphate ester is present in an amount of 15 wt % to 25 wt % based on the total weight of the composition, and the oligomeric phosphate ester has the structure (II) wherein R is independently a divalent C Z is independently selected from the group consisting of (i) monovalent C each m is independently 0 or 1, n is from 1 to 10; and the composition has (A) a Shore hardness of less than 50D as measured in accordance with ASTM D 2240, (B) an elongation at break from 300% to 650% as measured in accordance with ASTM D 638, and (C) a VW-1 rating as determined in accordance with method 1080 of UL-1581.
