EVA Foam for Gaskets and Seals: Material Selection and Performance

When it comes to ensuring effective sealing and cushioning in industrial applications, choosing the right material is paramount. Ethylene-Vinyl Acetate (Schiuma EVA) has emerged as a preferred choice for gaskets and seals, thanks to its unique blend of properties. At Damao, we specialise in providing high-quality EVA foam solutions that meet the demanding needs of a variety of industries.

What is EVA Foam?

Schiuma EVA is a closed-cell material made from the copolymerisation of ethylene and vinyl acetate. It combines the elasticity of rubber with the toughness of plastic, making it a highly versatile option. EVA foam is well-known for its excellent flexibility, resilience, water resistance, and chemical stability, all of which make it particularly suitable for gasket and sealing applications.

Why Choose EVA Foam for Gaskets and Seals?

1. Superior Sealing Capability

Due to its closed-cell structure, EVA foam offers excellent resistance to water, air, dust, and other contaminants. This makes it ideal for environments where maintaining a clean and controlled seal is essential.

2. Durability and Longevity

EVA foam can endure repeated compression and relaxation without losing its form, ensuring long-term performance. At Damao, our EVA foam products are engineered to withstand the rigours of both static and dynamic sealing environments.

3. Thermal and Chemical Resistance

The foam resists degradation from various chemicals and operates effectively across a wide temperature range. This ensures consistent performance in demanding industrial settings.

4. Lightweight and Customisable

One of the standout features of EVA foam is its low density, which makes it lightweight without compromising strength. Damao offers EVA foam in panels, rolls, and pre-cut finished items, allowing for tailored solutions to meet specific project needs.

Applications of EVA Foam Gaskets and Seals

EVA foam is widely used across several industries due to its adaptable nature. Common applications include:

• Automotive: Used in door seals, light housings, and dashboard gaskets.
• Electronics: Provides dust and moisture protection in enclosures.
• HVAC Systems: Ensures airtight seals to improve energy efficiency.
• Imballaggio: Prevents product movement and provides cushioning during transit.

Damao supports these industries with precision-engineered EVA foam components, enhancing performance and reliability.

Material Selection Considerations

When selecting EVA foam for gaskets and seals, several factors should be evaluated:

• Density and Hardness: Determines the foam’s compressibility and resilience.
• Spessore: Affects the foam’s ability to fill gaps and withstand compression.
• Environmental Exposure: UV, moisture, and temperature conditions must be considered.
• Adhesive Backing: May be required for ease of installation.

At Damao, our team works closely with clients to help select the ideal EVA foam formulation tailored to specific applications and operational environments.
