Closed Cell Foam Benefits

Closed-cell foam is a flexible and strong sealing material with cells that sit together closely. Polyethylene foam, EVA foal, nitrile foam, SBR foam rubber, and neoprene foam are all examples of closed-cell foams. As a comparison, cells in open-cell foams are broken, and the air is diffused into the substance. Usually, closed-cell foams are denser and heavier than open-cell foams.

Keeping that in mind, let’s take a look at the 6 key benefits of using closed-cell foam:

Impervious To Bacteria, Mildew And Rot - other than for insulation, closed-cell foams provide excellent resistance to bacteria, mildew, and rot. These foams don’t absorb water, and when used properly, they can provide a moisture barrier.

Resistant in Temperatures Between -60c And 90c - closed-cell foams are resistant in temperatures between -60c and 90c. This is useful for manufacturing companies who ship their products to areas with extreme climates.

Longer lifespan - closed-cell foams ensure a longer lifespan. Because they are lightweight, flexible and wear-resistant, closed-cell foams can last for decades and continue holding their shape and strength. Some open-cell foams may gradually lose their effectiveness, which may require re-insulation. This can cost more money and time.

Resistant To Mould Growth - due to their chemical composition, mould and bacteria can’t feed on closed-cell foams. Areas that have high humidity, such as basements, closed-cell foams, provide better protection. Foams with digestible, organic compositions will degrade over time and lose their ability to protect the home.

Better Structural Strength - closed-cell foams are lightweight and flexible and have higher compressive strength. They are also wear and tear-resistant, which means that these foams can improve rigidity and structural integrity of everything from shipping packages to soundproof rooms.

Buoyancy - closed-cell foam is known for its incredible buoyancy, and it is widely used throughout the marine industry.

Closed-Cell Foam Applications Include: • Shock Absorption • Packaging • Buoyancy Aids • Thermal Insulation • Kneeling Pads • Acoustic Sound Proofing

For waterproof insulation with excellent durability and thermal properties, closed-cell foams are a better choice. But for better soundproofing performance, open-cell foams are more preferable.
