Dow olefin block copolymers (OBC) are unique polyethylene materials that combine hard and soft segments into a single molecule and offer a variety of unique properties. These materials can be effectively used as elastic engines in applications such as diapers, providing clean, easy-to-process and consumer-friendly materials. The unique structure of the material and the ability to control the block structure allow the elastic performance of the material to be tailored to meet market needs. OBC materials are composed of both hard and soft segments of polyethylene which can be modified during production. The hard segments act as anchor points while the soft segments provide elasticity to the final film. Variations in the ratio of hard to soft segments can change the expected performance of the elastic film and bring elastic performance to sensitive hygiene applications where chemistry, performance and sensory experience are important. Elastic films utilizing OBC technology have the ability to power some of the most sensitive hygiene applications driven by ground breaking molecular designs.
