Performance, safety, and color stability: the new orange compounds for safer electric mobility, with LATI’s IATF 16949 certified quality to ensure total reliability and traceability.

In the latest generation of electric vehicles, the high voltages and currents used in traction systems and onboard services impose strict safety standards. One of these is the immediate visual identification of plastic components intended for high voltage management, which must be colored in a specific shade of orange.

However, prolonged exposure to high temperatures and adverse environmental conditions can cause color shifting, compromising not only the component’s aesthetics but also its risk signaling function. For this reason, thermal color stabilization in technical compounds represents a crucial challenge.

LATI Innovations for the Thermal Stabilization of Engineering Polymers

During 2024, LATI developed an advanced formulation of LATAMID 66 H2 G/25-V0HF1, a PA66 reinforced with 25% glass fiber, certified UL94 V0 for flame retardancy and characterized by a reduced environmental impact.
This new version, now available in orange, has passed severe thermal aging tests, demonstrating remarkable resistance to color shifting:

  • DeltaE ≤ 5 after 168 hours of exposure at 100°C

This solution, named OR:4349, complements the RAL 2001 version, already validated for exposures exceeding 1000 hours at 100°C.

Diversification of the Offer for Specific Needs

The different mechanical, thermal, and environmental requirements in the e-mobility sector demand a range of customized compounds for power lines. Among the main objectives:

  • Moisture resistance, to minimize absorption and reduction of mechanical properties.
  • Greater stability under static and dynamic stresses, even in critical thermal conditions.

To meet these requirements, LATI has developed heat-stabilized orange engineering polymers, based on different polymer matrices:

  • PBT reinforced with 30% glass fiber, available in a standard or UL94-V0 HF flame retardant version (halogen and red phosphorus-free). The LATER 4 G/30-V0HF1 showed acceptable color shifting after 1000 hours of exposure at both 125°C and 150°C.
  • PA9T (Aromatic Polyamide) flame retardant and glass fiber reinforced, ideal for extreme temperatures, now available in orange.

Innovation in the e-mobility sector requires advanced solutions that ensure safety, durability, and compliance with international regulatory standards. Thanks to the new technical compounds in orange, LATI offers materials capable of maintaining color and performance stability, even in extreme operating conditions.
