Addressing the Complex Demands of Electrified Vehicles
The transition to electric powertrains fundamentally reshapes material science requirements within the automotive industry. Components in an EV must withstand unique stresses, including high electrical loads, extreme thermal cycles, and intense electromagnetic interference.
LATI’s strategic consolidation of its specialized compounds underscores a holistic approach to material development, recognizing the multifaceted challenges faced by EV engineers and designers.
Enhancing Safety with Advanced Flame-Retardant Solutions
Safety remains paramount in electric vehicle design, particularly concerning high-voltage systems and battery components. LATI’s halogen-free flame-retardant (HFFR) compounds are engineered to mitigate fire risks effectively.
These advanced materials are built upon robust polymer matrices such as polyamide, polybutylene terephthalate (PBT), polyphthalamide (PPA), and polyphenylene sulfide (PPS). They are specifically rated for superior electrical insulation, intrinsic flame resistance, and exceptional long-term stability.
This stability is crucial for ensuring that components maintain their protective properties throughout the vehicle’s operational life, even under the most demanding environmental and mechanical conditions.
Ensuring Visual Integrity in High-Voltage Systems
In high-voltage (HV) circuits, standardized color coding is a critical safety measure, with orange serving as the universally recognized identifier. Maintaining this visual clarity over time is vital for technicians and emergency responders, preventing accidental contact with energized components.
Recognizing this, LATI has meticulously developed specialized HV formulations. These compounds are engineered to resist color shift and degradation during thermal aging, a common issue in components exposed to the inherent heat of an EV powertrain. Crucially, these grades also maintain their vibrant orange hue even in hot and humid environments, guaranteeing that a high-voltage component remains unmistakably identifiable across the vehicle’s entire service life.
Mastering Extreme Temperatures with High-Performance Polymers
Electric vehicles operate under increasingly high temperatures in various critical areas, from battery modules and power electronics to electric motors and inverters. Traditional engineering polyamides often struggle to meet the thermal demands of these advanced systems.

LATI addresses this challenge with a suite of high-performance polymer compounds, including PPA, PPS, polysulfone (PSU), polyethersulfone (PESU), polyphenylsulfone (PPSU), and polyetheretherketone (PEEK). These materials offer significantly elevated glass transition temperatures and continuous use temperatures, ensuring structural integrity and functional reliability where conventional plastics would fail, thus enabling robust designs for extreme thermal conditions.
Optimizing EV Thermal Management Through Conductive Plastics
Effective EV thermal management is indispensable for maximizing battery longevity, ensuring optimal powertrain performance, and preventing thermal runaway incidents. LATI’s LATICONTHER range represents a significant advancement in this domain, offering thermally conductive compounds designed to dissipate heat efficiently.
These specialized materials achieve thermal conductivity values of up to 28 W/mK by uniformly dispersing graphite and advanced ceramic fillers throughout the polymer matrix. To put this in perspective, an unfilled polyamide typically conducts heat at well under 1 W/mK.
While high filler loading is essential for achieving such figures, it can influence flow characteristics and mechanical performance. Nevertheless, LATICONTHER compounds empower designers to effectively transfer heat through plastic components, offering compelling alternatives to metal parts in selected applications where weight reduction, design flexibility, and corrosion resistance are key advantages.
Safeguarding Electronics with Robust EMI Shielding
The proliferation of high-power electronics, electric motors, and extensive wiring harnesses within an EV creates a complex electromagnetic environment. Electromagnetic Interference (EMI) can disrupt sensitive sensors, control units, and communication systems, compromising vehicle safety and performance.
LATI’s LATISHIELD compounds provide crucial protection by building an electrically conductive structure directly within the polymer matrix. Utilizing advanced fillers such as stainless steel fibers, carbon fibers, and nanotubes, these compounds deliver impressive shielding effectiveness, ranging from 30 to 90 dB.
This translates to a substantial reduction in field strength, from approximately 30-fold to an astounding 30,000-fold, ensuring the integrity of electronic signals and adherence to stringent electromagnetic compatibility (EMC) regulations.
Innovating for Reduced Friction and Wear
Beyond the core electrical and thermal demands, mechanical efficiency and durability remain crucial. LATI’s LATILUB formulations target applications requiring reduced friction and enhanced wear resistance. These compounds are engineered to minimize or, in many cases, entirely eliminate the need for external lubrication, offering significant advantages in terms of maintenance, system weight, and operational cleanliness.
Furthermore, the LATILUB range includes grades specifically formulated without per- and polyfluoroalkyl substances (PFAS). This commitment reflects a growing industry trend towards environmentally conscious material choices, addressing concerns over persistent chemicals while maintaining high performance in moving parts such as gears, bearings, and actuating mechanisms.
Driving Sustainability with Recycled Content Compounds
As the automotive industry increasingly embraces circular economy principles, the integration of sustainable materials becomes paramount. LATI’s LATIECO compounds underscore this commitment by incorporating raw materials derived from both mechanical and chemical recycling processes.
These sustainable grades are not limited to basic applications; they also include high-performance flame-retardant and thermally conductive options. The ability to combine recycled raw material with critical functionalities like thermal conductivity in a single compound represents a significant step forward, demonstrating that environmental responsibility can be seamlessly integrated with stringent performance requirements in the evolving EV landscape.
The Broader Impact: A Holistic Approach to EV Material Science
LATI’s initiative to consolidate these specialized thermoplastic compounds into a single technical resource highlights the growing complexity and integrated nature of modern EV engineering. The demands on plastic materials extend far beyond traditional lightweighting and metal replacement strategies.
Luca Posca, LATI’s Group Technical Assistance & Marketing Director, encapsulates this evolving paradigm, stating, “Electrification is significantly expanding the number of functions that plastic materials must perform inside the vehicle. It is no longer only a matter of lightweighting or metal replacement, but also of electrical safety, thermal management, electromagnetic shielding, high-temperature resistance and reduced environmental impact.” This perspective underscores the imperative for material innovation that addresses the full spectrum of challenges in electrified transport.
