Item Description

Foam Closed Cell Natural is an Ensolite closed cell PVN foam that is designed for flotation gear and marine cushions. Ensolite foam is 3 times as firm as polyurethane foam and resists moisture absorption, weather-aging, and mechanical abrasion. Ensolite does not support combustion. This closed cell foam is excellent to use for cockpit cushions, life jackets, bosun's chairs, or anywhere a firm, thin cushion is needed.

Glue pieces of foam together with adhesive to form custom foam shapes and sizes and to reduce waste.

Closed cell foam may shrink over time, especially in colder weather. Note that thicker foams tend to be more stable than thinner foams.

Sold per linear foot (full feet only). Maximum shipping length via UPS is 10 feet. This item may not be returned.
