Open cell EPDM foam is a flexible rubber foam material designed for applications requiring soft compression, vibration absorption and environmental resistance.

Unlike closed cell EPDM foam, open cell EPDM foam has an interconnected cellular structure, providing:

• Low compression force

• Excellent flexibility

• Fast recovery

• Good vibration absorption

• Weather and ozone resistance

AITO FOAM supplies customized open cell EPDM foam sheets, rolls and converted foam parts for automotive, industrial and acoustic applications.

What Is Open Cell EPDM Foam?

Open cell EPDM foam is manufactured from Ethylene Propylene Diene Monomer (EPDM) rubber through a controlled foaming process.

The internal cell structure is connected, allowing air to move between cells.

Key Characteristics

Main Advantages of Open Cell EPDM Foam

1. Low Compression Force

Open cell EPDM foam can achieve high compression with relatively low pressure.

This makes it suitable for applications where:

• Assembly force must be minimized

• Components require soft contact

• Surface protection is important

Typical applications:

✓ Automotive interior pads
✓ Electronic cushioning
✓ Equipment protection

2. Excellent Compression Recovery

The foam structure allows repeated compression and recovery.

Benefits include:

• Long service life

• Stable cushioning performance

• Reduced vibration transmission

3. Weather and Ozone Resistance

EPDM rubber provides excellent resistance against:

• UV exposure

• Ozone

• Outdoor aging

• Temperature changes

This makes EPDM foam suitable for demanding environments.

Open Cell EPDM Foam Applications

Automotive Industry

Open cell EPDM foam is commonly used in automotive applications requiring soft compression and noise reduction.

Typical Applications:

Note:

Open cell EPDM foam is generally used for cushioning, anti-rattle and vibration control.

For critical waterproof sealing applications, closed cell EPDM foam is usually recommended.

Speaker and Acoustic Applications

Due to its soft structure and recovery performance, open cell EPDM foam is suitable for:

• Speaker gasket materials

• Acoustic damping

• Vibration isolation

Advantages:

✓ Good compression recovery
✓ Stable contact pressure
✓ Noise reduction performance

Industrial Applications

Open cell EPDM foam can be used for:

• Machine cushioning

• Equipment protection

• Industrial sealing assistance

• Dust protection

Available processing:

• Foam sheets

• Foam strips

• Die-cut parts

• Adhesive backed foam
