WEB EXCLUSIVE: The Hygiene and Medical business of Dow Chemical Co., Midland, Mich., has introduced new grades of its high-molecular weight Infuse OBCs (Olefin Block Copolymers) for blown films. They are said to provide enhanced soft-stretch performance plus high elasticity for diaper components such as ears and waistbands.


Elastic laminates made with Infuse OBCs are said to offer the elasticity and softness that consumers prefer for diaper ears, waistbands and side panels. The soft-stretch performance of Infuse OBCs is the result of their lower glass-transition temperature than conventional propylene-ethylene copolymers, resulting in laminates that help maintain body-hugging fit without irritation. In addition, Infuse allows processors to customize the level of elasticity needed and helps products retain shape when worn and stretched, making Infuse OBCs a comparable yet cost-effective alternative to SBC (styrene block copolymer) elastic laminates, Dow says.
