Arkema showcased a full range of specialty materials and more sustainable solutions for use both inside and outside of electric vehicle (EV) and energy storage system (ESS) batteries.
Here are a few of the innovations Arkema showcased at The Battery Show this year:
Innovation Outside the Cell
Solutions for Thermal Management
XPU TCA 202
Bostik, Arkema's specialty adhesives business, introduced
thermal conductive adhesives (TCA) for bonding battery cells and managing heat in Cell-to-Pack designs.
The XPU TCA 202 is a two-component, polyurethane-based adhesive specifically designed for heat dissipation in battery pack assemblies. 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 to meet most stringent regulations and enables easy product handling without specific training. 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. The launch follows the recent announcement of the planned acquisition of Polytec PT by Arkema.
Oleris® Advanced Bio-Materials
100% Bio-based
Oleris® material for dielectric fluids for direct fluid immersion cooling systems is derived from renewable castor oil, enhances dielectric fluids in battery direct liquid immersion cooling systems. The 100% bio-based n-heptanoic acid and carbon-neutral C7 fatty acid enables the synthesis of high-performance polyol esters, resulting in dielectric fluids with low viscosity, lower pour point, excellent oxidation stability, and biodegradability.
This technology marks a major step forward in the development of more sustainable solutions for battery thermal management.
Solutions for Lower Energy-intensive Dielectric Insulation
With the emergence of electric mobility, new solutions that allow decarbonization are emerging. New solvent-free UV technology enables low energy consumption, instant drying and ease of application, which are key factors for efficiency and mass production of dielectric coatings for battery cells. The high performance Sartomer® UV curable specialties are enabling this transition, providing excellent dielectric properties, adhesion and flexibility.

By leveraging Group synergies with Bostik adhesive solutions and expertise, Arkema is identifying opportunities to develop solutions with unrivaled adhesion properties between the coated battery cells.
Lower Carbon Footprint Rilsan® Polyamide 11 for EV Busbars
100% Bio-based Rilsan® Polyamide 11, derived from renewable castor plants, for EV battery busbars, offers superior abrasion, thermal, and chemical resistance. Demonstrating its commitment to sustainability, Arkema has partnered with ENGIE to supply 300 GWh/year of renewable biomethane, further reducing the carbon footprint of Rilsan® Polyamide 11.
Innovation for more Circular “End Of Life”
Arkema is collaborating with the Rhinoceros Project, a consortium dedicated to advancing sustainable reuse and recycling in lithium-ion batteries across the European Union. Hosting a recent meeting, the members focused on cost-effective and sustainable technologies for battery materials recycling and reuse. Recovering and recycling KYNAR® PVDF, widely used as a battery cell electrode binder, was a key area of discussion.
