  • Tear resistant elastic crystal gels suitable for inflatable restraint cushions and other uses
    Patent number: 6627275
    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.

  • Gelatinous elastomeric optical lens, light pipe, comprising a specific block copolymer and an oil plasticizer
    Patent number: 4618213
    Abstract: A novel gelatinous composition is disclosed which contains an intimate melt blend admixture of poly(styrene-ethylene-butylene-styrene) triblock copolymer having said styrene end block to ethylene and butylene center block ratio within the range of from between 31:69 to 40:60, and high levels of a plasticizing oil.The gelatinous composition is transparent and have a novel combination of properties including unexpectedly high elongation and tensile strength and excellent shape retention after extreme deformation under high-velocity impact and stress conditions. The gelatinous products of this invention are soft, flexible, and have elastic memory, characterized by a gel rigidity of from about 20 gram to about 700 gram Bloom. These and other properties are particularly essential for the gelatinous composition to have utility as toys, therapeutic hand exercising grips, shock absorbers, acoustical isolators, and other uses.
