  • Acoustic insulator
    Patent number: 5484970
    Abstract: Disclosed is a novel acoustic insulator constituted by a shaped article obtained by adding a binder to shreds of a plastic coated with a magnetic material, such as a magnetic tape or magnetic sheet and shaping the same into a sheet or a block having a bulk specific gravity of 0.05 to 0.4 and a gas permeation resistance of 3 to 90 dyn.S/cm.sup.4. Alternatively, shreds of a plastic coated with a magnetic material, such as a magnetic tape or magnetic sheet, are filled into casing members so that the bulk specific gravity of the composite product is 0.05 to 0.4 and its gas permeation resistance becomes 3 to 90 dyn.S/cm.sup.4.
