Close Cell Foam Sheet Specifications
Close cell is a type of foam in which the “cells” are enclosed and tightly pressed together, contrasting with the open, interconnected cells of the open-cell, or traditional polyurethane foam variation. This means that water rolls of the sides rather than passing through the foam. With higher density and greater pressure resistance, this malleable material comes in a variety of forms. From the rigid polyethylene (cross-poly) foam to the squishy feel of Flotex, closed-cell foam is a versatile material offerring a tight seal and enhanced stability.
