A flexible pavement structure comprises a surface layer, a base layer, a sub-base layer, and a subgrade layer. Herein, the surface layer is adjacent to and above the base layer, and the sub-base layer is adjacent to and above the subgrade layer. The flexible pavement structure further comprises a layered system composed of first, second, and third materials different from each other, and is disposed as an interface layer between the base layer and the sub-base layer. The first material is a geotextile fabric selected from a group consisting of polypropylene and polyethylene, providing ground stabilization or reinforcement properties. The second material is a waterproof heat insulation material selected from a group consisting of cross-linked polyethylene foam and laminated aluminum foil, providing waterproofing or impermeability properties. The third material is a glass foamed insulation material.

A sound-absorbing material has an excellent sound absorbing property in a low-frequency range, an intermediate-frequency range, and a high-frequency range. The sound-absorbing material is a laminated sound-absorbing material, which includes at least one first layer, and at least one second layer that differs from the first layer. The first layer has a mean flow pore diameter of 2.0 to 60 μm and an air permeability according to the Frazier method of 30 to 200 cc/cm.sup.2.Math.s. The second layer is a layer including at least one kind selected from a foamed resin, a nonwoven fabric and a woven fabric, has a thickness of 3 to 40 mm, and has a density that is lower than the first layer and is 51 to 150 kg/m.sup.3. The first layer is disposed on a sound incidence side of the second layer.

A method for manufacturing a laminated molded body includes a cutting-out step for cutting out a cushion layer to form a cut-out part; a base material laminating step for forming a first laminated body; an insulating material placing step of attaching an insulating material to the cut-out part; a first thermocompression bonding step for bonding the first laminated body by thermocompression; a removing step for removing the cut-out part to form an opening; a skin laminating step for forming a second laminated body; and a second thermocompression bonding step for bonding the skin at the opening part to the lower layer material by bonding the second laminated body by thermocompression, the lower layer material being arranged below the cushion layer having the opening part.

An acoustic panel includes a front skin comprising a plurality of apertures, a back skin, and a core positioned between the front skin and the back skin. The core includes at least one primary core portion including a honeycomb structure defining a plurality of cavities extending from the front skin to the back skin. The core further includes a secondary core portion external to the at least one primary core portion and including a foam structure extending from the front skin to the back skin.

Isocyanate-reactive composition that include a polyol blend, a blowing agent composition, and a catalyst. The polyol blend includes a polyether polyol having a functionality of 2 to 6 and an OH number of 20 to 50 mg KOH/g, which is present in an amount of at least 30% by weight, based on total weight of the isocyanate-reactive composition, and an aromatic polyester polyol having a functionality of 1.5 to 3 and an OH number of 150 to 450 mg KOH/g, which is present in an amount of at least 40% by weight, based on total weight of the isocyanate-reactive composition. The blowing agent composition includes water, the water being present in an amount of 1 to 20% by weight, based on total weight of the isocyanate-reactive composition and in an amount of at least 90% by weight, based on total weight of the blowing agent composition. The isocyanate-reaction composition has a green content of at least 30% by weight, based on total weight of the isocyanate-reactive composition. Polyurethane foam-forming reaction mixtures, polyurethane foams, multi-layer composite articles and methods for their production are also described.

Tear and heat resistant foams used in packaging, protective packaging bags and related methods are provided. The tear and heat resistant foam can include a nonwoven substrate, a polyethylene film, and a base layer of polyethylene foam joined together by applying at least one of heat or heat and pressure to the top nonwoven substrate, the polyethylene film and the polyethylene foam to heat the first surface of the top nonwoven substrate to a temperature that is above the melting point of polyethylene film but below the melting point of top nonwoven substrate. The temperature of the polyethylene film rises causing the polyethylene film to melt and bind the top nonwoven substrate to the polyethylene foam to form the heat and tear resistant packaging foam.

Provided is a functional laminate including a porous intermediate layer having air permeability laminated between a porous surface layer and a resin foamed layer, the porous intermediate layer having an affinity to a foaming resin forming the resin foamed layer.
