Abstract: The present invention provides an apparatus for forming a polymer, comprising: a chamber having a predetermined pressure and storing a molten polymer resin; a foaming agent injection portion connected to the chamber and supplying a foaming agent, which is supplied from the outside, into the chamber by forming a pressure equal to or higher than the pressure inside the chamber; and a polymer backflow prevention portion provided at the foaming agent injection portion, and through which the supplied foaming agent passes so as to increase a contact surface area with the polymer resin, thereby preventing the backflow of the polymer resin.

Abstract: Disclosed herein is an adhesive composition for an insulator, the adhesive composition including a copolymer formed by using at least one type of phenol-based monomer; at least one type of monomer that is polymerizable by an alkali salt; and at least one type of monomer that is polymerizable by a bisulfate.

Abstract: Provided is a brick thermal insulation composite including a surface layer and an internal layer, wherein the surface layer is a brick material, the internal layer is formed with a heat curing foam insulation material, and the heat curing foam insulation material includes a foam resin and a fibrous reinforcement material.
