ISOVOLTA

The race to embrace cleaner and more efficient energy solutions has never been more intense. ISOVOLTA, a name synonymous with technological innovation, leads the charge with high-performance materials, and an unwavering commitment to safety in the energy industry.

ISOVOLTA is built on a foundation of quality and has accumulated over 70 years of experience producing technical laminates for different industrial applications.

By leveraging the knowledge gained from its initial journey of insulation high and low-voltage generators, ISOVOLTA is exploring how specialized materials can benefit other applications, including lithium-ion batteries used in cars. These batteries have the potential for thermal runaway, leading to fires with temperatures reaching up to 1200 degrees Celsius, which makes insulation important.

ISOVOLTA’s clients have recognized the safety risk posed by the lithium-ion battery packs used in cars and have turned to the company’s expertise to facilitate a suitable thermal insulation solution.

“While our insulation solution doesn’t prevent thermal runaway, it focuses on facilitating insulation materials that can contain flames within the battery enclosure and prevent them from entering the passenger compartment, thus significantly improving battery safety,” says Dr. Christiane Zenz, head of product management batteries, ISOVOLTA.

The unique strength of ISOVOLTA lies in combining over 300 different raw materials in roll form. The ability to laminate these diverse materials together and afterward convert the composite materials according to customer specifications is a crucial part of its core competencies regarding battery safety technology.

ISOVOLTA takes these functional raw materials, including in-house manufactured mica paper, and combines them through lamination to create innovative products tailored to specific customer requirements. The applications include thermal insulation, fire protection, electrical insulation, and, upon request, features like compressibility and ballistic resistance.
In addition to laminating, it produces essential raw materials in-house, particularly for fire protection applications within battery technology. One of the primary materials is mica paper, a heat-resistant paper derived from stone, capable of withstanding temperatures exceeding 1,200 degrees Celsius.

Its diverse product range is preferred by clients from more than 20 different industries, including electronics, aviation, and engineering. The adaptable solution provider is known for rapid response times, quick prototyping capabilities, and comprehensive product consultation and testing services.

ISOVOLTA's battery insulation portfolio is called Thermiga. ISOVOLTA's thermal propagation protection battery packaging materials can address thermal insulation, UL94 V0 – fire protection, electrical insulation, compressibility, technical cleanness, and ballistic resistance requirements.

While the high and low-voltage insulation materials remain a focal point, ISOVOLTA's expertise transcends this sector. It is recognized for delivering high-quality materials for battery applications such as thermal propagation materials. The company's flexible and modular approach enables it to tailor its products to meet multiple customer requirements.

Innovation is at the heart of ISOVOLTA's mission. It aspires to be a technology leader and one-stop solution provider for customers. From rapid prototyping to well-equipped test laboratories, it offers comprehensive support, ensuring its products exceed industry standards.

ISOVOLTA's impressive global footprint, with production sites in Asia, the US, and Europe, allows it to stay close to customers and meet high-volume demands. This flexibility and agility set it apart in a rapidly changing industry. It is also in close contact with numerous European OEMs and has secured a nominated supplier status for Volkswagen in motor insulation.

The company aims to contribute significantly to thermal and electrical solutions within battery packs. ISOVOLTA's legacy of excellence, innovation, and safety positions it at the forefront of the energy revolution, where every innovation brings the industry one step closer to a safer and more sustainable future.
