Abstract: In an embodiment of the present disclosure, a process for producing a flexible pouch is provided. The process includes placing a capillary precursor element (CPE) between two opposing flexible films. The flexible films define a common peripheral edge. The CPE comprises an array of pins sandwiched between two opposing polymeric strips. The process includes positioning a first side of the CPE at a first side of the common peripheral edge and positioning a second side of the CPE at a second side of the common peripheral edge. The process includes first sealing, at a first seal condition, (i) the opposing polymeric strips to each other to form a matrix, and (ii) sealing the matrix to the two opposing flexible films. The process includes removing the array of pins from the matrix to form an in situ microcapillary strip.

Abstract: A continuous process for preparing insulation panels having thick (0.2 mm to 1 mm) metal facing panels and a fiber-reinforced polymer foam core is disclosed. In the process, a bottom metal facing panel is continuously supplied. A mat of reinforcing fibers and a foamable resin composition are applied to the bottom facing panel. A flexible barrier layer is applied atop the foamable resin composition, and the assembly is passed through nip rolls to compress the assembly and force the resin composition into the fiber mat. An adhesive layer and top metallic facing layer are then applied on top of the flexible barrier layer, and the resulting assembly is gauged and cured by passing it through a double band laminator.
