Key Findings
Henkel Adhesive Technologies has introduced an innovative, next-generation thermal gap filler, Bergquist Gap Filler TGF 6500LVO, designed to meet the escalating thermal management demands of automotive electronics. This new product boasts a high thermal conductivity of 6.5 W/m∙K, enabling it to effectively manage the high heat loads generated in advanced applications such as electric vehicles (EVs), Advanced Driver-Assistance Systems (ADAS), and power conversion components within Electronic Control Units (ECUs).
Technical & Clinical Details
- Superior Thermal Conductivity: The Bergquist Gap Filler TGF 6500LVO delivers a market-leading thermal conductivity of 6.5 W/m∙K, facilitating efficient heat transfer from heat sources to heat sinks. This capability prevents overheating of electronic components, thereby stabilizing performance and enhancing overall reliability.
- Two-Component Silicone Base: The material is a two-component, silicone-based formulation, offering excellent flexibility and reliability post-cure. It can be applied with a low bond line thickness (BLT) and easily conforms to complex geometries and narrow gaps, ensuring superior adhesion.
- Addressing Increasing Power Density: Modern automotive electronics, including ADAS sensors, EV power electronics, and ECUs, are becoming increasingly miniaturized and sophisticated. This trend leads to higher power densities and greater heat generation. This product is engineered as an optimal solution to mitigate these challenges.
Background & Industry Context
The automotive industry’s rapid evolution towards electrification and autonomous driving technologies has dramatically increased its reliance on in-car electronics. Consequently, efficiently managing the heat generated by critical components such as batteries, motors, inverters, and ECUs has become paramount for vehicle safety, performance, and longevity. As traditional thermal management materials struggle to keep pace, innovative solutions like those from Henkel are increasingly in demand.
Strategic Significance & Outlook
The introduction of Bergquist Gap Filler TGF 6500LVO further solidifies Henkel’s leadership in the automotive electronics market. This new technology directly contributes to extending EV range, improving ADAS system accuracy, and enhancing the overall reliability of automotive electronic systems. It is expected to become a foundational technology supporting future innovations in the automotive sector, driving the development of even higher thermal conductivity and more versatile thermal management materials.
