  • Publication number: 20190248938
    Abstract: The invention provides a fluoroelastomer composition capable of providing a molded article that is inexpensive and has excellent heat-aging resistance. The fluoroelastomer composition is a peroxide-crosslinkable fluoroelastomer composition containing a fluorine-containing elastomer that contains 25 to 90 mol % of a unit of vinylidene fluoride, 10 to 75 mol % of a unit of a fluorine-containing monomer other than the vinylidene fluoride, 0 to 10 mol % of a unit of a fluorine-free monomer copolymerizable with the vinylidene fluoride, and 0.1% by mass or less of an iodine atom and a bromine atom; an organic peroxide having a specific structure; and a co-crosslinking agent. The organic peroxide is present in an amount of 0.3 to 10 parts by mass relative to 100 parts by mass of the fluorine-containing elastomer.

  • Publication number: 20190248941
    Abstract: This invention relates generally to the field of quasicrystalline structures. In preferred embodiments, the stopgap structure is more spherically symmetric than periodic structures facilitating the formation of stopgaps in nearly all directions because of higher rotational symmetries. More particularly, the invention relates to the use of quasicrystalline structures for optical, mechanical, electrical and magnetic purposes. In some embodiments, the invention relates to manipulating, controlling, modulating and directing waves including electromagnetic, sound, spin, and surface waves, for pre-selected range of wavelengths propagating in multiple directions.
