(15) is closed and clamped in place; and, the reactive Components "A" and "B" are allowed to foam and expand in an exothermic reaction, whereby the expanding material (12) is forced into, entirely through, and entirely throughout the open cell foam sheet (10) with excess material (12...
Based on the assumptions of the foaming process and the microstructure characteristics of foam,open-cell and closed-cell models with single-centered cubic(SCC),face-centered cubic(FCC) and body-centered cubic(BCC) array are constructed.The relationships between relative density and structural parameters...
but the material is usually hard due to the incompressibility of the gases in them. In terms of resistance to liquid permeability, closed-cell materials are superior to open-cell materials. In addition to its strong resistance to compression set, open-cell foam is softer, more breathable and ...
