Thermal Management for Automotive Electronics

Automotive innovation continues to be fueled by advances in electronics capability and the increasing integration of these technologies into modern vehicles. The prioritization of emission reduction, safety, fuel efficiency, high reliability and superior performance relies on high-functioning electronic automotive systems which, consequently, place increasing demands on thermal performance.


More densely populated circuit boards, high-powered battery technology, power steering modules and massive engine control capability all demand unfailing thermal management for reliable function. Henkel’s comprehensive portfolio of GAP PADS, liquid dispensed GAP FILLERS, SIL-PADS and phase change thermal interface materials are meeting the challenging requirements for supporting energy efficiency, safety-critical components for autonomous driving, and next-generation electric vehicles platforms.

Automation-enabled High Throughput

When speed, high throughput and exceptional thermal control are the challenges, GAP FILLERS are the solution. Applied via automated dispensing systems, GAP FILLERS facilitate high-volume production speeds while sacrificing nothing in the way of thermal management capability. Two-part GAP FILLERS are dispensed quickly, flow in and around even the most delicate circuitry, form in place and compensate for the large tolerances between the heat-generating device and its housing or heat sink counterpart.

Supply Chain Simplification - Icon

Supply Chain Simplification

Liquid, form-in-place GAP FILLERS are adaptable to multiple applications, allowing single part sourcing for a variety of different jobs. Instead of ordering large quantities pads or films – where each variety of size and thickness is a different part number – a single GAP FILLER product can satisfy thermal control requirements for several products. Simply dispense where needed, the material forms in place and thermal control is achieved. One product, many applications.

Low Component Stress - Icon

Low Component Stress

As compared to thermal pads, liquid thermal interface materials lower overall component stress. Even though pads are soft, the compression applied to the pads once they are placed puts stress on components. GAP FILLERS, on the other hand, require significantly less force to wet out the liquid. These unique materials flow into all of the voids of even the most delicate circuitry and then cure in place to form a solid pad-like structure, which also safeguards against shock, vibration, drop, expansion and mechanical stress.
