Abstract
A sound damping article is formed from a thermoplastic elastomer compound that includes styrenic block copolymer, high softening point tackifier, plasticizer, and secondary polymer. 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 sound damping article exhibits useful vibration damping properties while also exhibiting beneficial sound and/or noise damping properties at or above room temperature.
