摘要： An article is formed from a thermoplastic elastomer compound that includes styrenic block copolymer and high softening point tackifier. The styrenic block copolymer has a Copolymer Tan Delta Peak Temperature and the thermoplastic elastomer compound has a Compound Tan Delta Peak Temperature. The Compound Tan Delta Peak Temperature is greater than the Copolymer Tan Delta Peak Temperature. The article exhibits useful damping properties at or above room temperature while also exhibiting low compression set, which makes the article especially suitable for use as a seal or a gasket.
