Key Findings
Henkel announced two innovative thermal management materials for the electric vehicle (EV) market in May 2026. These materials play a crucial role in enhancing the efficiency and lifespan of EV batteries. Specifically, the Bergquist TGF 2030APS thermal gap filler achieves a high thermal conductivity of 1.7 W/m·K, while the Loctite TLB 9270APS thermal conductive adhesive reaches 2 W/m·K. These advancements are critical for the reliability and performance improvement of EVs.
Technical Details
The Bergquist TGF 2030APS is designed to effectively fill gaps between battery cells and cooling systems, facilitating efficient heat transfer to maintain a uniform temperature across the battery pack. This mitigates the risk of performance degradation and premature aging due to overheating. The Loctite TLB 9270APS combines strong adhesion with high thermal conductivity, making it ideal for applications requiring both structural integrity and heat dissipation.
Concurrently, Hoenle Adhesives introduced a new UV-curable formed-in-place gasket material in March 2026. This technology allows for rapid curing during the manufacturing process, contributing to improved production efficiency and cost reduction in electronic and automotive components that demand precise sealing.
Background and Context
With the rapid expansion of the EV market, battery safety and performance, particularly thermal management, have become paramount challenges. High temperatures accelerate battery degradation and can, in severe cases, lead to thermal runaway. Therefore, highly efficient thermal interface materials and reliable sealing technologies are indispensable for the widespread adoption and performance enhancement of EVs.
Strategic Significance and Outlook
These new products provide EV manufacturers with advanced options for designing high-performance and safe battery packs. The importance of thermal management materials will continue to grow, especially as batteries with higher energy densities are developed. Ongoing innovation in adhesives and sealants will serve as a foundational pillar supporting the sustainable growth of the entire EV industry.
