    Abstract: Latex spray foams formed from a non-aqueous two-part foamable composition are provided. The A-side contains includes a dry latex polymer, a multifunctional acid, and a liquid blowing agent and the B-side contains a polyfunctional aziridine crosslinking agent a plasticizer, and, optionally, a non-functionalized resin. The multifunctional acid may be a secondary emulsion that is added to the composition separately. The polyfunctional aziridine crosslinking agent may be diluted by a plasticizer, which reduces the viscosity of the B-side. The plasticizer should have no acidic protons to react with the crosslinking agent. When no acidic protons are present, the B-side is stable for extended periods of time. Additionally, the inventive foam and composition are desirably free of water. The lack of water or small amount of water in the inventive foam composition permits the foam to be sprayed at temperatures below freezing and to a greater thickness compared to water-containing compositions.

    Abstract: The present invention provides a crosslinked polyolefin-based resin-extruded foam sheet capable of reducing its thickness while retaining excellent flexibility and heat resistance. The crosslinked polyolefin-based resin foam sheet of the present invention is obtained by feeding a polyolefin-based resin and a thermally degradable blowing agent to an extruder, melting and kneading them, extruding the kneaded material through the extruder into a sheet to form an expandable polyolefin-based resin sheet, and expanding the sheet. Herein, a degree of crosslinking of the crosslinked polyolefin-based resin foam sheet is 5 to 60% by weight, an aspect ratio of a cell (MD average cell diameter/CD average cell diameter) is 0.25 to 1, and the polyolefin-based resin contains 40% by weight or more of a polyethylene-based resin obtained using a metallocene compound containing a tetravalent transition metal as a polymerization catalyst.

    Abstract: A method for producing a cross-linked PVC rigid-foam body from a starting mixture containing PVC, an isocyanate or polyisocyanate, an organic anhydride and a chemical expanding agent by: converting the starting mixture into a molded article inside a compacting device under the action of pressure and heat; removing the article from the mold, and; expanding and hardening the obtained molded article in an expanding device while supplying heat and water and/or water vapor whereby forming a cross-linked PVC foam body. The starting mixture contains epoxidized compounds in amounts greater than 3% by weight, preferably greater than 5% by weight, and less than 15% by weight with regard to the starting mixture.
