In the design of fluid handling and sealing systems, we know there is no such thing as a “universal” material. At ILPEA, the key to success lies in selecting the material whose chemical structure is optimal. This allows it to respond precisely to the thermal, chemical, and mechanical stress of each application. Put simply: whatever delivers the best cost and quality for our customers.
How do we configure our lines with these specific materials?
Cooling Lines: Our commitment to TPV efficiency
For cooling lines, TPV (Thermoplastic Vulcanizate) is our go-to standard.
Why do we choose it? Because we successfully combine the compression set resistance of rubber with the lightweight properties of plastics. This technical advantage allows us to withstand constant thermal cycles without losing flexibility, ensuring our connections remain perfect throughout the vehicle’s entire service life.
Cleaning & Fluid Lines: Multi-layer technology and versatility
Whether we are designing a cleaning line or a venting/feeding line, we play with the material’s rigidity and structure.
In this field, our technical capability sets us apart: we offer multi-layer solutions combining up to 5 functional layers. This allows us to integrate barrier properties, chemical resistance, and mechanical flexibility into a single tube—performance that a single material simply could not achieve.
- Thermoplastics (PA, PP, PPS): We use them when our priority is absolute impermeability and pressure resistance. PPS, for example, offers exceptional performance in ultra-high temperature environments where other plastics would fail.
- EPDM: We maintain it in specific fluid lines for its excellent resistance to atmospheric aging and temperature. It remains our trusted material for liquid transport.
Sealing Profiles: The balance between EPDM and TPV
In our sealing profiles, we consider the material’s “memory” to be vital:
- EPDM: Our choice when maximum elastic recovery and total weather resistance (UV and Ozone) are required.
- TPV: We opt for this solution when seeking a lighter, more sustainable component (100% recyclable) with tighter dimensional tolerances than traditional vulcanized rubber allows.
Why are we reducing the use of steel?
At ILPEA, we are fully aligned with global decarbonization trends. Replacing steel (Stainless/Carbon) with technical polymers is not just an option; it is our engineering strategy:
- Weight Reduction: By replacing metal with technical plastics like PPS or reinforced PA, we decrease the energy consumption of the final system.
- Carbon Footprint Optimization: The processing of our thermoplastics requires significantly less energy than metal casting and machining.
- Corrosion Elimination: With our polymers, we eliminate the risk of oxidation at its core, without the need for additional chemical coatings.
At ILPEA, we don’t just manufacture profiles or tubes; we select the right chemistry and the precise structure so that every component is the strongest link in the system.
