Patent ID: 8552117

Claim:
A polymeric sealing element comprising or obtainable from a composition, comprising: a styrenic block copolymer; an olefin block copolymer including two or more different olefin blocks, each olefin block including olefins having from 2 to about 12 carbon atoms; polyolefin polymers comprising a first polyolefin polymer having a melt index less than 10 grams per 10 min; a second polyolefin polymer having a melt index greater than 10 grams per 10 min, and a softener, wherein the olefin block copolymer and the styrenic block copolymer are each present in an amount of less than 50 parts by weight per 100 parts by weight of the total polymer of the polyolefin polymers, the olefin block copolymer and the styrenic block copolymer, and wherein the polyolefin polymer is present in an amount by weight greater than each of the amounts of the styrenic block copolymer and olefin block copolymer, wherein melt index is determined according to ASTM D-1238.
