Abstract
A thermoplastic elastomer compound 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 thermoplastic elastomer compound exhibits useful damping properties at or above room temperature while also advantageously possessing improved stability for processing and/or applications at high temperatures and upon exposure to weathering.
