In a sector as demanding as nuclear power, where each component must combine strength, durability, traceability and compliance, the choice of materials is strategic. And among them, silicone stands out as a discreet but decisive ally.
At PROGRESS Silicones, we have been designing tailor-made solutions for the nuclear industry for over 40 years, taking advantage of all the unique properties of this versatile material.

The advantages of silicone for nuclear power

1. Extreme resistance to severe conditions

‍
Silicone is capable of operating in a temperature range of —110°C to +315°C.
It remains stable against ionizing radiation, corrosive or saline environments, as well as UV.

‍
2. Unparalleled adaptability

‍
This material can be very flexible or very hard, depending on the mechanical constraints of your installations.
It is also colorable, conducting or insulating.

‍
3. An exceptional outfit over time

‍
Unlike other materials that degrade during thermal cycles or exposure to aggressive environments, silicone maintains its physical properties over time.
A major asset in an industry where maintenance rhymes with rigor.

‍

Concrete applications in the nuclear sector

‍
Silicone is used in a wide variety of critical equipment, in particular for:
• Technical seals (flat seals, O-rings, inflatable seals...)
• Protective covers against splashes, heat or radiation
• Flexible connectors or insulating sheaths to secure electrical connections
• Vibration-absorbing or damping parts in sensitive environments
• Thermal or electrical insulation elements embedded in cabinets or control panels
• Parts entirely designed to measure, such as this room dedicated to the collection of radioactive waste.

‍
All these parts are custom-designed, according to the specific needs of each site, each machine, each normative requirement.

A controlled transformation, in the heart of Provence

‍
At PROGRESS Silicones, we have an integrated production tool in the PACA region, in the heart of Luberon.

‍
Our expertise is based on:
• A design office to co-develop your projects
• Flexible processes (extrusion, moulding, manufacturing)
• An ISO 9001 standard and compliance with industry standards
• Rigorous traceability, essential for the nuclear sector
