Closed cell foam floats well because of the structure of the foam itself.
The cells of the foam are closed meaning they're not inter-locking as in open cell foam structure. Because the foam cells are closed this gives the foam good buoyancy in that the form itself cannot become saturated with liquids causing it to sink. Uses for polyethylene in floatation applications include life-jackets, and other personal floatation devices.
The less dense the material the more buoyancy it provides. Closed cell foam is also used in water craft in much the same manner it is used in the aerospace industry by placing it between the inner and outer hulls of boats ranging in size from small personal craft such as kayaks, to craft as large as speed boats and military attack craft.
