Bostik and Polytec PT Launch a New Thermal Conductive Adhesive Range for Battery Pack Assemblies

Bostik and Polytec PT have collaborated to launch a new range of thermal conductive adhesives (TCA) to address the challenge of thermal management in the latest Cell-to-Pack (CTP) battery design for e-mobility solutions.

The two companies report that thermal management is vital to ensuring the operating temperature of EV-Battery systems remains between 20°C and 40°C for optimum battery life and performance. Thermal interface materials (TIM) such as TCAs are essential to battery design to ensure a robust thermal connection between the battery/cell environment and the cooling elements. With the trend towards fast charging for e-mobility, the importance of thermal management – and TIMs – is increasing significantly.
The new XPU TCA 202 is a two-component, polyurethane-based adhesive specifically designed for heat dissipation in battery pack assemblies. According to the companies, it perfectly tackles the challenge to balance thermal conductivity with high mechanical strength while maintaining good levels of flexibility thanks to high elongation. Its low-monomer content allows it to meet most stringent regulations and enables easy product handling without specific training.
The companies report that, at a practical level, it is also fast and easy to process through automatic mixing, dosing and dispensing equipment. It adheres well to most substrates without using a primer, and cures at room temperature.
