Common Applications of Closed-Cell Foam

Closed-cell foam is a versatile material that is beneficial in various industries due to its unique structure and properties. The term “closed-cell” refers to the internal makeup of the foam, where cells (or bubbles) are completely enclosed, providing a dense, non-permeable surface. This structural composition makes closed-cell foam resistant to water, air, and gas penetration, making it an ideal material to use in applications that require insulation, shock absorption, or water resistance.

Packaging and Shipping

Closed-cell foam is commonly used in packaging to protect delicate items during shipping. Its dense, yet lightweight nature provides excellent shock absorption and cushioning. This type of foam is commonly found in custom foam inserts to ensure that fragile items like electronics, glassware, or medical instruments can be shipped safely without damage. Because closed-cell foam is resistant to water and chemicals, it is also a reliable material for long-term storage of sensitive items. Volara foam is a popular choice for many art galleries to protect delicate artwork and artifacts.

Marine Applications

Due to its buoyancy and water-resistant properties, closed-cell foam is a popular option in marine environments. It is often used to provide flotation in boats, docks, and life jackets. In marine construction, closed-cell foam is used as flotation billets or within the hull of a boat to maintain buoyancy, even if the boat takes on water. The closed-cell structure minimizes the absorption of water, helping to maintain its buoyant characteristics.

Automotive and Aerospace Industries

Closed-cell foam is used in the automotive and aerospace sectors for soundproofing, vibration dampening, and thermal insulation. It helps to reduce noise and vibration in vehicles, improving passenger comfort. In aircraft, the material’s lightweight properties contribute to fuel efficiency, while still providing the necessary insulation and shock absorption.

Healthcare Products

Closed-cell foam is also found in medical applications. You see it used in prosthetics, orthotics, and padding for braces due to its comfort, durability, and non-absorbent nature.

Sports Equipment

Closed-cell foam is vital to the safety of athletes in many different sports. The foam is used in helmets, protective padding, and mats, providing shock absorption and cushioning during high-impact activities.

Closed-cell foam’s versatility makes it a crucial material across industries, offering insulation, protection, flotation, and more. To find out more about how SEKISUI Voltek can provide you with effective closed-cell foam solutions, like our range of Volara® products, please contact us.
