Interep designs and manufactures high-performance elastomeric foams, also known as Foam rubber, for sealing, damping, insulation, and protection functions. ADDEV Materials distributes and transforms these materials for Power & Mobility applications, with a focus on EPDM and Microshock® foams intended for railway and EV battery environments.
Interep solutions are tailored to constraints of compression, vibration, ageing, temperature, and sequential integration. ADDEV Materials converts them into seals, adhesive tapes, die-cut parts, profiles, and ready-to-integrate kits.
Interep is a French specialist in elastomeric cellular foams. The brand develops materials based on EPDM, EPDM blend, NBR, CR, EVM, NR/SBR, and other formulations intended for demanding industrial applications.
Interep foams are used when a component needs to perform multiple functions: air/water/dust sealing, vibration dampening, shock absorption, thermal insulation, or secondary electrical protection.
For the rail and e-mobility markets, ADDEV Materials favours EPDM and Microshock® foams for their balance of compressibility, resilience, environmental resistance, and ability to be transformed into technical parts.
Interep foams are selected when the sealing or damping function needs to remain stable despite compression cycles, vibrations, moisture, temperature fluctuations, and exposure to industrial environments.
La gamme couvre des densités de 75 à 500 kg/m³, des duretés Shore 00 de 15 à 80 et des compressions de 10 à 500 kPa à 25% de déformation. Ces paramètres permettent d’ajuster précisément le comportement d’un joint, d’un spacer ou d’une pièce anti-vibration.
Durable waterproofing under low compression

ADDEV Materials offers Interep foams in several families and formats to meet the sealing, compression, insulation, and dampening requirements of railway, battery, and industrial systems.
| Range | Material | Main function | Typical applications |
|---|---|---|---|
| EPDM Foam | EPDM foam rubber | Waterproofing, insulation, environmental resistance | Rail joints, battery modules, external interfaces |
| EPDM Blend | Modified EPDM | Performance / cost / ageing resistance trade-off | Automotive, e-mobility, industrial equipment |
| Microshock® | Impact absorption mousse technique | Mechanical protection, comfort, shock absorption | Equipment protection, anti-vibration pads, damping parts |
| CR / NBR Foam | Technical elastomers | Resistance to oils, fuels and harsh environments | Industry, energy, technical sealing |
| Converted parts | Processed mousses ADDEV | Ready-to-fit parts | Gaskets cut, adhesive tapes, profiles, kits |
The choice of an Interep foam depends on density, compression, temperature, chemical environment, sealing level and integration format.
Interep performance depends on the elastomer formulation and cell structure. The parameters below guide material selection during the design or industrialisation phase.
-55°C to +150°C depending on formulation.
75 to 500 kg/m³ to adjust mass, compression, and mechanical strength.
10 to 500 kPa depending on grade and application.
Shore 00 from 15 to 80 depending on the foam family.
Sealing, insulation, damping, anti-vibration, impact absorption.
Ageing, ozone, oils, fuels and humidity depending on formulation.
FMVSS / UL 94 compliant references as required by the application.
Blocks, plates, rollers, profiles, adhesive tapes and cut parts.
Interep foams are used in Power & Mobility systems where sealing, damping, insulation or mechanical protection needs to remain reliable over time.
ADDEV Materials transforms Interep foams into ready-to-install parts: gaskets, adhesive tapes, spacers, anti-vibration pads, profiles, and application kits. Converting ensures geometry, tolerances, adhesion, and production repeatability.
Choosing Interep with ADDEV Materials secures the selection of foam and its industrial integration:
Are you looking for EPDM foam, Microshock®, or a converted part for railway, EV battery, or industrial applications? ADDEV Materials will assist you in choosing the material, density, compression, adhesion, and final format.
An Interep EPDM foam is a cellular elastomeric foam used for sealing, insulation and damping. It is suitable for environments subjected to moisture, ageing, ozone and compression cycles.
Microshock® is an Interep solution focused on impact absorption and mechanical protection. It is used when a part needs to absorb shock energy, reduce vibration, or protect sensitive equipment.
For a railway application, the choice depends on the function: sealing, damping, insulation or protection. EPDM foams are relevant for seals and interfaces exposed to vibration, moisture and environmental stress.
An EPDM foam can provide sealing, mechanical compensation and vibration damping within a battery pack. It helps to stabilise interfaces and protect components against mechanical stress.
A closed-cell foam acts as a barrier and promotes watertightness. A more open structure facilitates absorption and flow management. The choice depends on the level of compression, permeability, and protection expected.
ADDEV Materials can supply Interep foams in blocks, sheets, rolls, profiles, adhesive tapes, cut parts, gaskets, pads, spacers and kits. The formats are adapted to the customer's process and assembly constraints.
The choice depends on the available compression effort, the required level of sealing, the thickness, the geometry, and the expected service life. For a gasket, initial compression, compression set, and long-term stability must be balanced.
