Abstract:
An article comprising a laminate, wherein the laminate comprises:(a) a first rigid layer formed from a material selected from the group consisting of glass and plastic;(b) a second rigid layer formed from a material selected from the group consisting of glass and plastic;(c) a vibration damping material layer(s) comprising a viscoelastic material positioned between the first rigid layer and the second rigid layer, wherein the vibration damping material layer(s) has a loss factor of at least about 0.1 at 20.degree. C. and 10 Hz and a thickness of about 0.01 mm to about 0.8 mm; and(d) a first layer of a flexible plastic positioned between the first rigid layer and the vibration damping material layer(s), wherein the first layer of flexible plastic is of such a nature that a test construction of the layer of flexible plastic laminated between two sheets of annealed glass, each sheet of annealed glass having a thickness of 2.5 mm, would pass the Consumer Product Safety Commission test 16CFR, Part 1201, Category I; and(e) optionally a second layer of a flexible plastic positioned between the second rigid layer and the vibration damping material layer(s) wherein the second layer of flexible plastic is of such a nature that a test construction of the second layer of flexible plastic laminated between two sheets of annealed glass, each sheet of glass having a thickness of 2.5 mm, would pass the Consumer Product Safety Commission test 16CFR, Part 1201, Category I.
