Closed 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.
EVA Foam is a firm closed-cell foam with a softer, more rubbery feel than our polyethylene (cross-poly) offering. Its surface squishes down when you press your fingers into it, quickly bouncing right back into place. The firm structure and UV resistance of EVA foam makes it a great material for outdoor applications, and it is also popular for use as a Cosplay material. It weighs 2 lbs/ft³, and is commonly used for products like decking on boats, surfboards, knee pads, helmet padding, insulating hot tubs, shin guards and excercise mats.
