Mastering sealing means mastering performance

In critical systems, sealing gaskets don’t just block fluids. They protect components, ensure interface reliability, and ensure compliance with the most demanding standards.

That’s why we design custom sealing solutions, adapted to extreme environments and high mechanical stresses.

The 4 key criteria for defining functional and environmental constraints

1

Define the sealing function Airtight, watertight, or gastight ? Protection against electromagnetic interference (EMI/RFI)? Thermal or vibration insulation ?

2

Identify the environment Working temperature Pressure exerted on the seal Presence of fluids, solvents, dust, UV rays, ozone Mounting conditions: fixed, mobile, subject to vibration.

3

Define the mechanical constraint Static or dynamic, it influences the compression rate and the geometry of the gasket.

4

Integrate applicable standards Depending on your sector (aeronautics, railways, defense, electronics, etc.), certain standards may apply: IP67/IP68 for waterproofing UL 94 for fire resistance MIL-DTL-83528 for conductive seals RoHS / REACH for environmental compliance

What are the most commonly used materials?

Each polymer or composite has its own technical signature:

Technical silicone: ideal for thermal and UV environments, with excellent flexibility.

EPDM: recommended for outdoor applications, thanks to its resistance to ozone and humidity.

Fluorosilicone: essential in the presence of hydrocarbons or aggressive solvents.

Conductive composites: integration of a conductive seal using a coextrusion principle to ensure electromagnetic shielding (EMI/RFI) and electrical conductivity, while maintaining sealing properties.

All of our formulations are designed to meet precise specifications, with materials tested in the laboratory and validated in real-life conditions.
