SOLUTIONS · AUTOMOTIVE MATERIALS
Thermal materials built for the vehicle.
Battery, sensor, and under-hood thermal materials, qualified for the temperature range, vibration, and service life of automotive platforms.
The Challenge
The harshest thermal environment there is.
Automotive electronics operate from −40 °C to +150 °C, endure constant vibration up to 20 g, and must last 15 years or 300,000 km. Battery management modules, ADAS sensors (LiDAR, radar, cameras), and under-hood ECUs all generate heat that must be conducted away without material degradation. A gap filler that pumps out or a coolant that loses inhibitor protection can cause a field recall, making material qualification as critical as the component design itself.
HeTone supplies automotive-grade battery gap fillers, sensor TIMs, coolants, and structural adhesives from Henkel, Parker Chomerics, Jeffcool, and ExxonMobil, pre-qualified against AEC-Q200, LV 124, and OEM-specific reliability standards. We support PPAP documentation and lot traceability for Tier 1 supply chains.
