Foam is commonly used in various marine applications, from engine insulation and sound absorption to constructing boat seats. Moreover, it has buoyancy capabilities and offers a multitude of distinct features.

For buoyancy applications, closed-cell foams are the most effective types of foam to use. Closed-cell foam is stronger and more stable than open-cell foam, and it resists water and air leakage better. Closed-cell foam is highly suitable for marine applications, particularly buoyancy.

Buoyancy foams are customizable in size, shape, and color through molding, vertical and horizontal cutting.

Characteristics of EVA Buoyancy Foam

The EVA buoyancy foam is recognized for its exceptional buoyancy and distinctive traits which consist of.


EVA’s lightweight is due to thousands of small interconnected bubbles.

Thermal Insulation

EVA foam prevents pipes from freezing in winter and protects floating pipes in colder temperatures. Additionally, it serves as a shield against heat transfer to insulated spaces during hot seasons.

Sound Insulation

By using EVA foam, the sound of boat and ship engines is prevented from entering the cabin, and it also prevents the sounds generated in the vessels from being transmitted to the water, which could harm marine life. Therefore, the hulls of ships and boats are insulated using EVA foam.

High Durability

Higher quality foams result in a more extended product life. These foams are resistant to seawater, oils, acidic and alkaline substances, and other chemical materials.

Water Resistance

Materials utilized in marine buoyancy applications should resist hydrolysis, that is, they should not easily decompose when submerged in water.

Mold and Bacteria Resistance

EVA foam’s closed-cell structure makes it indispensable in buoyancy applications related to water because it doesn’t foster the development of mold and bacteria.

EVA Foam’s Uses in the Shipbuilding Industry

EVA is a closed-cell foam type that prevents slipping on decks and covers various surfaces on the vessel, such as boat and ship hulls. EVA foam is popular because it doesn’t absorb water.

Docks also make extensive use of EVA foams. Dock edges are protected from boat and ship hull damage by installing them in desired dimensions and sizes.

In case of emergency, EVA foams serve as a flotation device. The buoyancy foam slows the sinking speed significantly if a vessel is punctured and water enters. The buoyancy foam usually allows for enough time to rescue or reach the shore before the boat sinks. When there is sufficient foam on the ship, it can prevent total sinking and safeguard the lives and possessions of those on board.
