Is a high performance olefin block copolymer with high elasticity and soft stretch in cross direction (CD) for improved fit and comfort for hygiene elastic films. This low density, high performance olefin block copolymer is easily processable on a wide range of cast and blown film equipment, offering high elastic recovery and low force profiles. It can be combined with other olefin block copolymers such as INFUSE™ 9507 Olefin Block Copolymer or INFUSE™ 9100 Olefin Block Copolymer to finely tune elastic and mechanical properties of cross-direction and machine-direction elastic films. Furthermore, it can be used for high performance shoe soles.
