Battery Electronics

Battery Electronics

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 Electronics

ARALDITE® and ARATHANE® encapsulants for batteries assure protection of sensitive devices, improve thermal management, and meet the most stringent temperature requirements. They offer high flexibility and crack resistance, optimized thermal conductivity, and excellent thermal endurance, as well as improved chemical stability.

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.
