Silicone foam: high-performance solutions for demanding industrial environments

Silicone foam is a high-performance technical material designed to withstand the most demanding conditions in industrial environments. It is characterised by its exceptional resistance to extreme temperatures, its durability and its sealing properties, making it the preferred solution for critical applications.

Used in demanding sectors such as energy, rail, electronics and HVAC systems, it guarantees long-term reliability even under extreme conditions.

At ADDEV Materials, we support manufacturers in selecting and custom-processing silicone foams to optimise the performance, safety and durability of their equipment.

Silicone foam for industrial applications

In an industrial environment, silicone foam is used for :

  • sealing critical systems
  • thermal and electrical insulation
  • absorb mechanical stress
  • protect sensitive components

It is particularly relevant in applications where other materials reach their limits.

Silicone foam is a premium material:

  • more resistant than PU or PE foams
  • better temperature resistance than EPDM
  • more sustainable in extreme environments

It is the preferred choice when performance and long-term reliability are the top priorities.

What is silicone foam?

Silicone foam is an expanded elastomer material with a cellular structure, designed to offer high performance in demanding environments.

It is characterised by :

  • excellent temperature stability (both high and low)
  • high compressive strength
  • excellent waterproofing
  • resistance to UV light, moisture and chemicals

It is particularly well suited to applications requiring long-term stability and high reliability

Silicone foam vs. other foams: What's the difference?

Silicone vs EPDM

  • silicone → high temperature, durability
  • EPDM → standard sealing, lower cost

Silicone vs PU

  • silicone → extreme resistance
  • PU → sound absorption

Silicone vs PE

  • silicone → flexibility + temperature
  • PE → rigidity + optimised cost

The choice depends on the technical requirements of your application.
