Versatile foams – for industry, trade & technical applications

Foams are used wherever reliable sealing, insulation, decoupling or protection is required. Depending on the material type, they offer different properties such as moisture resistance, elasticity, thermal or sound insulation. Typical areas of application include mechanical and plant engineering, building services, vehicle construction as well as maintenance, repair and assembly work.

Material and Properties

The foams in this category are manufactured from EPDM cellular rubber, comparable to sponge rubber. Key properties include a closed-cell structure ensuring 100% water resistance, high compressibility combined with strong recovery forces, and durable self-adhesive backing with grid reinforcement for enhanced bond strength. All products are manufactured in Germany.

Applications

EPDM cellular rubber foams are widely used for sealing, insulating, and cushioning tasks across various industries. Typical applications include weatherproofing joints and gaps, vibration damping in machinery, and moisture-resistant sealing in construction and automotive contexts. The closed-cell structure and water resistance make these foams particularly suited for outdoor and wet-environment installations.

Frequently Asked Questions

EPDM cellular rubber foam is used as a sealing, insulating and cushioning material. Its closed-cell structure makes it ideal for applications where waterproofing, vibration damping or thermal insulation is required, such as in construction, automotive and mechanical engineering.

Yes, our EPDM cellular rubber foam sheets come with a grid-reinforced, high-tack self-adhesive backing. This ensures strong and reliable bonding to a wide range of surfaces without the need for additional adhesive.

Yes, the EPDM cellular rubber foam is closed-cell, making it 100% waterproof. It does not absorb moisture, which makes it suitable for outdoor applications and environments exposed to water or humidity.

The EPDM cellular rubber foam is available in DIN A4 format, which measures approximately 210 x 297 mm. This standardised size makes it easy to handle and cut to your specific requirements.

Our EPDM cellular rubber foam is manufactured in Germany. It meets premium quality standards, ensuring consistent material properties and reliable performance.

The EPDM cellular rubber foam is highly compressible and offers strong recovery forces. This means it can be significantly compressed under load and will reliably return to its original shape, making it excellent for sealing and cushioning applications.

Our EPDM cellular rubber is comparable to traditional sponge rubber (Moosgummi) but features a closed-cell structure. This gives it superior waterproofing and weather resistance compared to open-cell sponge rubber materials.

Yes, the DIN A4 sheets can be easily cut to size using scissors, a craft knife or a cutting plotter. The self-adhesive backing remains functional on cut pieces, allowing flexible use in custom applications.

Yes, EPDM is inherently resistant to weathering, UV radiation, ozone and temperature extremes. Combined with its closed-cell, waterproof structure, the foam is well suited for long-term outdoor applications.
