TIM-Tester – Vespel – Thermal conductivity, Thermal Impedance in Polymers
Glass Adhesive – Thermal conductivity
The adhesive being examined has applications in structural bonding, with a particular emphasis on glass sealing in vehicles. This adhesive offers a broad spectrum of mechanical properties, making it versatile for sealing gaps in vehicle battery packs and for various automotive components like quarter lights, modular roof assemblies, sunroof systems, and door glass.
Some of its notable advantages include high thermal conductivity, low thermal resistance, effective vibration damping, and compatibility with all vehicle production processes. The primary objective of the TIM-Tester measurement was to confirm the adhesive’s thermal conductivity.
The plot illustrates a measurement of the thermal impedance (thermal conductivity) of the adhesive at a temperature of 37 °C, with a specified temperature gradient of 6 °C. During the measurement, pressure was incrementally increased to compress the sample further, resulting in a decrease in thickness from 3 mm to 2 mm.
The determined thermal conductivity value was 1.76 W/mK, aligning with the expected results.
