In the phenolic resin foam laminate board (10), a surface material (2) is arranged on at least one of one side of a phenolic resin foam (1) and the back side of the one side. The phenolic resin foam (1) has a density of not less than 22 kg/m.sup.3 and not more than 50 kg/m.sup.3, a cell diameter of not less than 50 μm and not more than 170 μm, and a closed cell ratio of not less than 80%. When HCFO-1224yd(Z), aliphatic hydrocarbons having a carbon number of 6 or less, chlorinated saturated hydrocarbons having a carbon number of 5 or less, and hydrofluoroolefin are gas components, the phenolic resin foam contains only HCFO-1224yd (Z) as a gas component. A cell internal pressure of air bubble is 0.20 atm or more.

A product includes an aerogel having a single bulk structure, the single bulk structure having at least one dimension greater than 10 millimeters. The single bulk structure includes a plurality of pores, where each pore has a largest diameter defined as a greatest distance between pore walls of the respective pore. In addition, an average of the largest diameters of a majority of the pores is within a specified range, and the plurality of pores are distributed substantially homogenously throughout the single bulk structure.

A structure (piping part (121)) has a cured product of a thermosetting resin composition (resin molded body (101)) and a plating layer (103) formed on a surface of the cured product, in which the plating layer (103) has a Cu layer (second plating layer (107)) and a thickness of the Cu layer (second plating layer (107)) is 2 μm or more and 50 μm or less.

Drying polar solvents which do not form hydrogen bonds with a wet gel or aerogel, or eutectics or solvent mixtures with the drying solvents, are utilized in a solvent exchange with wet gels used in the formation of aerogels. Preferably the drying solvents are non-polar solvents. The drying solvent or solvent mixtures results in profoundly less shrinkage, thereby allowing for the production of aerogels of preferred materials properties.

A phenolic foam and method for manufacturing same are described herein. The foam comprises at least on chlorinated hydrofluoroolefin, at least one hydrofluoroolefin and at least one hydrocarbon. The foam has excellent thermal insulation performance and excellent fire performance.

A foamable composition for injecting in a region of a ship, for example to prevent and/or reduce water ingress and/or progressive flooding in the ship so as to improve damage stability of the ship, is foamable to form a foam and is dissolvable in a removal composition. The provision of a foam, which can be dissolved by application of a removal composition, e.g., a solvent, may improve ease of removal of the foam, and therefore may reduce the cost and/or speed of reinstatement of the ship. The present invention also relates to a method of improving damage stability of a ship, the method comprising identifying one or more regions of the ship where injection of a material may lead to increase in ship stability, the material being impermeable to water and/or being capable of preventing migration of water.

Provided is a phenolic resin foam laminate board in which a flexible surface material is arranged on at least upper and lower surfaces of a phenolic resin foam. The phenolic resin foam contains HCFO-1224yd(Z), has a density of not less than 20 kg/m.sup.3 and not more than 55 kg/m.sup.3, a closed cell ratio of 80% or more, an average cell diameter of not less than 60 μm and not more than 200 μm, a percentage of an area seeping out from the surface material is 30% or less, and content of HCFO-1224yd(Z) per space volume of 22.4×10.sup.−3 m.sup.3 in the phenolic resin foam is not less than 0.06 mol and not more than 0.35 mol.

A phenolic foam and method for manufacturing same are described herein. The foam is formed from a foamable phenolic resin composition, and a blowing agent, the phenolic foam comprising 1 to 5% by weight of red phosphorus based on the weight of the phenolic foam wherein said phenolic foam has a density of from 10 kg/m.sup.3 to 100 kg/m.sup.3, a closed cell content of at least 85% as determined in accordance with ASTM D6226 and wherein said foam has a FIGRA.sub.0.2 MJ of 120 W/s or less, when measured according to EN13823 and a thermal conductivity of 0.023 W/m.K or less, at 10° C., in accordance with EN 13166:2012. The foam has excellent thermal insulation performance and excellent fire performance.

Process for preparing rigid polyurethane or urethane-modified polyisocyanurate foams from polyisocyanates and polyfunctional isocyanate-reactive compounds in the presence of blowing agents wherein the polyfunctional isocyanate-reactive compounds comprise an unmodified or modified novolac polyol and a polyether polyol having a hydroxyl number of between 50 and 650 mg KOH/g obtained by reacting a polyfunctional initiator first with ethylene oxide and subsequently with propylene oxide wherein the propoxylation degree is between 0.33 and 2 mole propylene oxide per active hydrogen atom in the initiator and wherein the molar ratio of ethylene oxide to propylene oxide in said polyether polyol is at least 2.
