Abstract
An airbag copmrising crystal gels is disclosed. The crystal gel comprises one or more block copolymers having at least one crystalline midblock and high levels of a plasticizer. The midblock segment has an amount of crystallinity sufficient to achieve improvements in one or more physical properties including improved crack propagation resistance, improved tear resistance, improved resistance to fatigue and resistance to catastrophic failure.
