Bostik and Polytec PT launch new thermal conductive adhesives
Bostik and Polytec PT are launching a new range of thermal conductive adhesives (TCAs) for thermal management in the latest cell-to-pack battery designs for e-mobility solutions.
Thermal interface materials (TIMs) such as TCAs are essential to battery designs to ensure a robust thermal connection between the battery/cell environment and the cooling elements. The companies say that with the trend towards fast charging for e-mobility, the importance of thermal management and TIMs is growing swiftly.
The new XPU TCA 202 is a two-component, polyurethane-based adhesive designed for heat dissipation in battery pack assemblies. It is said to balance thermal conductivity with high mechanical strength while maintaining good flexibility thanks to high elongation.
Its low-monomer content allows it to meet the most stringent regulations and enables easy product handling without specific training.
At a practical level it is also fast and easy to process using automatic mixing, dosing and dispensing equipment. It adheres well to most substrates without using a primer, and cures at room temperature.
