Abstract
A thermoplastic elastomer compound includes a polyolefin elastomer blend of at least two different polyolefin elastomers, styrene-ethylene/butylene-styrene block copolymer, and plasticizer. The compound has a Melt Flow Rate (230° C., 2.16 kg) of no less than about 5 g/10 min and a Melt Flow Rate (190° C., 2.16 kg) of no less than about 1 g/10 min. Elastomeric films formed from the compound can be used in place of elastomeric films based on styrene-isoprene-styrene (SIS) block copolymers to make components of disposable hygiene articles.
