摘要： Provided are a foam molded body capable of improving damping properties and sound insulation properties of a panel and realizing weight reduction of a panel, a dam rubber, a complex of a dam rubber and a panel, and a method for increasing a sound transmission loss.
The present invention is concerned with a foam molded body of a resin composition containing a block copolymer (I) which is a block copolymer having a polymer block (A) composed mainly of a structural unit derived from an aromatic vinyl compound and other polymer block (B), exhibits a peak top temperature of tanδ, as measured under a condition of a thickness of a test piece of 1 mm, a strain amount of 0.1%, a frequency of 1 Hz, a measurement temperature of -70 to 70°C, and a temperature rise rate of 3°C/min in conformity with JIS K7244-10 (2005), of -50 to 50°C, and has a peak top molecular weight determined in terms of standard polystyrene by gel permeation chromatography of 30,000 to 500,000; at least one olefin-based polymer (II) selected from the group consisting of an ethylene-propylene-diene copolymer rubber, an ethylene-vinyl acetate copolymer, and a polyethylene-based resin; a crosslinking agent (III); and a foaming agent (IV).

摘要： The present invention relates to an interlayer film for a laminated glass, comprising in sequence an A layer, a C layer, and an A layer, and comprising at any place between or outside these layers, a B layer, wherein each A layer is a layer containing a first thermoplastic resin, a resin material constituting each A layer has a peak at which a tan δ measured by performing a complex shear viscosity test under a condition of a frequency of 1 Hz according to JIS K 7244-10: 2005 is maximum in a range of -30°C or more and 10°C or less, the resin material of at least one layer of the A layers has a height of the peak of a tan δ of 1.5 or more, the C layer is a layer composed of an inorganic glass having a thickness of 0.1 mm or more and 1.5 mm or less, or a layer having a thickness of 0.25 mm or more and 2.5 mm or less and containing a third thermoplastic resin, and when the C layer is the layer containing a third thermoplastic resin, a resin material constituting the C layer has a tensile storage elastic modulus at 0°C measured by performing a dynamic viscoelasticity test under a condition of a frequency of 0.3 Hz according to JIS K 72444:1999 of 1.0 GPa or more, and the B layer is a layer containing a second thermoplastic resin, and is constituted of a resin material different from the resin material constituting the A layer.
