Battery Packs

Battery Packs

The battery is the key component of any electrified vehicle, and improving battery efficiency, safety and cost are top priorities for vehicle designers. Encapsulation technology is a valuable tool to address these issues. Huntsman offers casting and impregnating resin systems for batteries, wire harnesses, connectors, sensors, switches and electronic control units.

Reliable Chemistry for Battery Packs

In order to optimize vehicle performance and extend its range, the new generation of EVs requires high power batteries: ARATHANE® thermally conductive adhesives provide at the same time mechanical fixation and thermal connection, enabling effective management of the heat coming from the cells over lifetime. 

Huntsman ARALDITE® and ARATHANE® potting materials are an excellent choice also to assure intercell protection, enabling absorption of vibrations and mechanical shocks and, contemporary, they provide a safety barrier against the introduction of moisture in challenging environmental conditions. The most stringent safety requirements are possible to meet thanks to improved thermal conductivity and flame retardant properties.

Resins act as a thermal interface between battery cells and active cooling elements, eliminating the need for mechanical connections.

They can also provide damping for vibration control, insulate high-voltage cables, and seal battery electronics to protect them from moisture, dust and chemicals. Our encapsulants are long‑lasting and provide reliable sealing. They are ready for the high-voltage applications (800 volts) that are required for the next generation of electric vehicles.

Huntsman offers a choice of epoxy-based and polyurethane resins. All are fast-curing even at low temperatures, which improves production throughput and delivers cost savings.

Frequently Asked Questions

What properties are required in encapsulants for battery electronics?

Encapsulants for battery electronics must exhibit maximal heat conductivity, and must be able to meet flammability certifications such as UL 94.

What specific Huntsman products are recommended as encapsulants for battery electronics?

ARALDITE® CW 1312 resin / ARADUR® HY 1300 hardener meets UL flammability certification 94 V-0 (3.2 mm). It cures at room temperature and has a low glass transition temperature. This translates to low thermally-induced stress.
