Advanced Thermoplastics for Electric and Sustainable Mobility

The transition to electric and hybrid mobility is profoundly transforming the automotive sector.
In addition to replacing combustion engines with electrified systems, future vehicles integrate autonomous driving technologies, advanced sensors, and high-power density electronic modules.

In this scenario, there is a growing need for lightweight materials capable of effectively managing heat while maintaining high mechanical strength and chemical resistance.
This is where thermoplastic compounds for thermal management come into play, developed to replace metals and alloys in structural and functional applications.

LATICONTHER MI: Thermoplastic Compounds for Thermal Management in the Automotive Sector

The LATICONTHER MI line, designed by LATI Industria Termoplastici, represents a new generation of structural thermally conductive materials for the needs of modern automotive.

These high-performance thermoplastic compounds combine:

  • High thermal conductivity, to promote heat dissipation from electronic modules and power components;
  • Superior mechanical strength, even in critical environments;
  • Chemical compatibility with lubricants, coolants, and other engine fluids;
  • Low density, to contribute to the overall weight reduction of the vehicle.

Composition and Properties of LATICONTHER MI Compounds

LATICONTHER MI compounds are based on a PA66 matrix reinforced with 35% glass fiber, stabilized to ensure consistent performance over time even in the presence of high temperatures and aggressive chemical agents.

Material structure

  • Polymer matrix: Thermally and chemically stabilized PA66
  • Reinforcement: 35% glass fiber
  • Thermally conductive additives: selected to maximize heat flow while maintaining mechanical integrity
  • Density: <1.6 g/cm³

The result is a material that dissipates up to 10 times more heat compared to traditional reinforced compounds, without sacrificing stiffness or tensile strength.

Performance of LATICONTHER MI01 and MI02 Grades

Property LATICONTHER MI01 LATICONTHER MI02
Technical objective Maximize mechanical strength Optimize thermal conductivity
Thermal conductivity (W/mK) ~2 (longitudinal) ~5 (longitudinal) / ~1 (transverse)
Tensile strength (MPa) ~150 ~120
Elastic modulus (GPa) 13 15
Density (g/cm³) <1.6 <1.6
Typical applications Structural supports, brackets, housings Heat sinks, integrated thermal components

The properties of both materials allow for optimal thermal management of electronic systems and power modules (inverters, converters, sensors), combined with structural robustness and fatigue resistance.

Advantages over Metallic Solutions

The thermoplastic compounds for automotive thermal management offer numerous advantages over traditional metals (aluminum, steel):

Aspect Metal Thermoplastic compound
Weight High Reduced (-50%)
Workability Requires mechanical processing Direct injection molding
Thermal conductivity High Medium-high (up to 5 W/mK)
Electrical insulation Poor Excellent
Chemical resistance Limited to surface treatments Intrinsic
Recyclability Medium High (thermoplastic)

These characteristics make the compounds ideal for multifunctional structural components, where thermal management, rigidity, and electrical insulation must coexist.

Applications in Electric and Hybrid Vehicles

The LATICONTHER MI compounds are suitable for a wide range of applications in the electric mobility sector:

  • Cooling systems for batteries and electronic modules
  • Structural supports for electric motors and inverters
  • Power housings for converters and control units
  • Dissipative plates and components for integrated thermal management

The combination of lightweight, thermal performance, and mechanical stability makes them a strategic choice for the design of new generation vehicles.

Innovation and Continuous Development

In addition to PA66-based compounds, variants based on PP, PBT, and PPS are being developed to address specific needs:

  • Improved chemical resistance;
  • Greater dimensional stability at high temperatures;
  • Optimization of processability for high-volume molding.
