There is disclosed a phenol resin foam which contains a phenol resin, and a foaming agent comprising at least either one of a chlorinated hydrofluoroolefin or a non-chlorinated hydrofluoroolefin. With respect to the phenol resin foam, a density is 10 kg/m.sup.3 or more and 150 kg/m.sup.3 or less, a thermal conductivity under a 10 C. environment is 0.0175 W/m.Math.k or less, and a thermal conductivity under a 23 C. environment is 0.0185 W/m.Math.k or less.

A method for producing a foam board laminate having low surface irregularities, the method comprising (i) preparing a continuous foam laminate; (ii) cutting the foam laminate to a desired length; (iii) placing the foam laminate of desired length into restriction to restrict further expansion of the foam laminate in the thickness of the foam laminate.

Floor panel for forming a floor covering, where the floor panel includes a carrier on the basis of a thermoplastic material and a top layer provided on the carrier. The thermoplastic material is free from plasticizers or includes a plasticizer in an amount up to maximum 20 phr, where the thermoplastic material is foamed or expanded, and where the carrier is provided with a reinforcement layer.

[Problem] The problem that unevenness occurs in the foam layer and the insulating property deteriorates when lamination is carried out at high speed was clarified in a process for producing a sheet for a foam insulating paper container. Specifically, the problem addressed by the present invention is to provide a sheet for a foam insulating paper container that can be foamed without unevenness even when laminated at high speed. [Solution] The present inventors discovered that the problem addressed by the present invention can be solved by a method for producing a sheet for a foam insulating paper container in which a polyethylene resin is laminated on at least one side of a paper substrate, wherein the method for producing a sheet for a foam insulating paper container is characterized in that the lamination conditions are an air gap of 150 mm or greater and a take-off speed of 70 m/min or higher.

Provided are a constrained-type vibration-damping metal sheet having foam pores and a method for manufacturing same. The constrained-type vibration-damping metal sheet of the present invention comprises: a lower metal sheet; a foam resin film bonded to the lower metal sheet; and an upper metal sheet bonded to the foam resin film, wherein the foam resin film has foam pores comprising, by wt % of itself, 85-95% of a thermoplastic polyethylene resin having a number average molecular weight of 8000-12000, 0.1-1% of stearic acid, 1-5% of a styrene-ethylene-butadiene-styrene (SEBS) resin, 0.5-5% of a foaming agent, 1-4% of a dicumyl peroxide crosslinking agent, and 0.5-2% of ZnO foaming aid.

This invention relates to a surface finish manufacturing system and process and more particularly, but not exclusively, to a contrast surface finish manufacturing system and process for producing boards with a wood texture finish. The surface finish manufacturing system comprises a top layer and a bottom layer where part of the top layer is removed to expose part of the bottom layer.
