VORATRON™

Polyurethane Systems

Enhancing automotive battery pack assembly

Cheerful African American couple in a car

VORATRON™ Polyurethane Systems allow for the development of thermally conductive and non-thermally conductive adhesives, gap fillers, and pottants for a wide range of battery types, such as prismatic, pouch, and cylindrical cells.

These customizable, two-part, room temperature curing polyurethane systems include low densities that allow for lighter weight powertrains, enabling reduced vehicle weight and reducing CO2 emissions, ideal for hybrid and electric vehicles.

Discover our full range of applications to find the solution that fits your needs and drive the future of H/EV battery systems forward.

Strong, reliable battery pack adhesives are crucial for the success of H/EV batteries and H/EVs. If your adhesive weakens, battery life and vehicle performance can be severely impacted. Our ample portfolio of solutions ensures bonds with long-lasting strength to maintain performance under harsh conditions.

Looking to build stronger bonds? VORATRON™ MA 8200 Series Polyurethane Systems meet the most demanding performance and quality needs of virtually any cell or battery type.

Aligned with the evolution of H/EV battery technology, these potent adhesives enable traditional cell-to-cell bonding as well as the more recent cell-to-module and cell-to-pack bonding methods. As this product line expands, it will also allow for the next step in the bonding evolution with cell-to-chassis bonding.

Powerful and customizable performance

Car part

VORATRON™ MA 8200 Series Polyurethane Systems provide exceptional performance across a range of low to medium thermal conductivity. Along with extremely high bonding strength, VORATRON™ MA 8200 adhesives feature toughness and elasticity, as well as rheokinetics, that can be adjusted and optimized to meet specific customer needs.

These high levels of performance are achieved through both effective rheokinetics for battery assembly with low abrasion materials to minimize wear and tear on dispensing equipment, filler content and types can also be customized to meet unique needs.

Our desire for strong bonds doesn’t begin and end with VORATRON™ systems. By partnering with our customers, we’re able to develop innovative, efficient, and sustainable solutions to advance the future of mobility. Please fill out our Contact Us form to learn more about VORATRON™ Polyurethane Systems and our robust portfolio of advanced battery pack adhesive solutions.

Applying gap filler

Almost every H/EV battery system requires some type of thermally conductive, polymeric gap filler to assist in attaching the battery to its cooling plate. As batteries for vehicles become higher performing with increased energy density, get your fill of what you need with Dow’s high-performing gap fillers in vehicles and in the assembly line.

Optimal performance, processing, and sustainability

Potting foam agent

Reliability. Ease. Stability. Large cylindrical battery designs are a popular choice for manufacturing H/EV batteries. While they burn less energy than pouch and prismatic designs, our battery pack pottants foams and encapsulants have individual cells and the entire battery covered to ensure thorough protection.

VORATRON™ Polyurethane Systems for potting foams and encapsulants offer mechanical strength as well as flexibility for the structural needs of the battery pack. These strong & tough foam pottants can also be modeled tailored to meet the rheokinetics that best suits different processing and assembly needs. Computational assistance helps design the properties and filling conditions to ensure that the dispensed pottant fills the intricate geometries and space of the cylindrical cell case, preventing voids that may lead to mechanical integrity issues of the pack.

Firm, Flexible, and Tough

Rigid battey cylinder

The ability to provide lightweight foam allows for efficient assembly to keep cells and the battery in place while providing the mechanical properties to ensure the structural integrity of the pack. Their inherent low density helps our VORATRON™ systems to produce lighter and more sustainable batteries through vehicle light-weighting and reduced carbon emissions.

With decades of materials science under our belt, our systems are developed with predictive intelligence capabilities to ensure the optimal mix of polyurethane, catalysts, surfactants, and additives and create desired results.
