Closed-cell foam primarily uses non-ozone depleting hydroflurocarbons (HFC’s), while open-cell primarily uses water. The formulations result in differing expansion reactions with closed-cell expanding about 35 to 50 times its original volume compared to open-cell which expands triple that to 150 times is original volume.

Web22 de mai. de 2024 · Closed-cell foam has a higher R-value than open-cell foams, which makes them more suited for extreme temperatures. In terms of expansion, an open-cell can expand up to 120 times its original size because of its lower density. A closed-cell, on the other hand, can only expand up to 33 times its original size. Web18 de jun. de 2024 · Open cell foam is more flexible and softer than closed cell foam, which has a higher core density of two to three pounds per cubic foot.
