Guillaume Desurmont, Senior Vice President, Bostik said that the launch of the new TCA is the first outcome of a fruitful collaboration between Bostik and Polytec PT. “With Polytec PT’s expertise in thermal conductive materials and Bostik’s expertise in structural polyurethane adhesives, we strengthen our offer with innovative Thermal Interface Materials (TIM) solutions to our customers in the Electric Vehicle (EV) battery market.”
Prasanna Rao, Business Director, Bostik India added, “The import of this significance can be seen in India, with the country pushing forward vigorously towards electrification. There is a distinct correlation between increasing calls for lightweight and safety materials in the automotive sector and the innovation of electric vehicle adhesives.”
The battery is a core component of an EV. While it is an essential component for the vehicle to function well, battery safety has utmost importance for the safety and protection of the passengers. TCAs provide the optimal solution – they not only bond the components together but are able to dissipate heat as well as absorb shock and vibration during the drive thus preventing damage to the sensitive components.
As EV technology progresses, the requirement for more reliable and effective adhesives to protect their batteries increases. Such capabilities contribute a crucial role to India’s environment and economy considering how approximately one-fifth of the country’s total energy use is attributed to its transportation sector.
“Our efforts to research and develop TCAs are more vigorous than ever. Effective thermal management in EVs ensures the reliability and robustness of EVs and enhances the performance of the vehicles,” Prasanna elaborates.
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. TIMs 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 result of Bostik’s cognizance of the need for an efficacious adhesive for their manufacturing partners is the new XPU TCA 202, a two-component, polyurethane-based adhesive specifically designed for heat dissipation in battery pack assemblies. It perfectly tackles the challenge of balancing thermal conductivity with high mechanical strength while maintaining good levels of flexibility thanks to high elongation.
