The present disclosure provides a laminated structure with a through hollow structure having heat insulation, a light weight, durability, and sound absorption performance to reduce wind noise, transmitted noise, and the like. The laminated structure of the present disclosure has a foamed resin layer having continuous pores containing fused resin foam particles, and an air-impermeable outer layer provided on one side of the foamed resin layer, where a part of the foamed resin layer of the laminated structure cut out with a diameter of 41.5 mmϕ has an amount of air permeability of 2.5 cm/(cm·s) to 40 cm/(cm·s) measured by the Frazier method in which the foamed resin layer is set as an air introduction side.

Laminated structure

Provided are a foam molded product and a method of producing the same. The foam molded product is a molded product containing a resin and including a surface layer, a compressive deformation layer, and a foam layer. The thickness of the surface layer is 0.1 mm to 5.0 mm. The compressive deformation layer is located between the surface layer and the foam layer. Foam particles forming the compressive deformation layer have an average H/L of 0.5 or less (H: length in compression direction; L: length in perpendicular direction relative to compression direction). Foam particles forming the foam layer have an expansion ratio of not less than 3.0 times and less than 30 times.

Foam molded product and method of producing same

Provided are resin foam particles that enable shaping of a sound absorbing member having excellent sound absorption performance through a resin foam shaped product. Also provided is a laminate that includes a resin foam shaped product as a base material and with which high sound absorption performance can be obtained even when the laminate is a thin material. The resin foam particles contain a resin and have a recessed external part. A ratio &#x3c1;/&#x3c1;of density of the resin &#x3c1;and true density &#x3c1;of the resin foam particles is 2 to 20, and a ratio &#x3c1;/&#x3c1;of true density &#x3c1;of the resin foam particles and bulk density &#x3c1;of the resin foam particles is 1.5 to 4.0.

Resin foam particles, resin foam shaped product, and laminate

A composition obtained by adding at least one specific elastomer and optionally a polyamide resin or a bromine-containing flame retardant to a melt-kneaded product of a polyphenylene sulfide with a non-blocked type polyfunctional isocyanate compound. The composition is excellent not only in impact resistance but also in aging resistance at high temperatures. Said composition can be advantageously used for molding parts of automobile engines, parts for various machines, connectors for electric or electronic parts, bobbines and the like.
