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.

VORATRON™ GF-1000 Series Polyurethane Systems provide efficient application with safe handling and use. These two-part, room temperature cure materials as well as low abrasion components, offer excellent processability. Like all VORATRON™ products, their low density allows for lighter weight materials which reduce vehicle weights and carbon footprints. Moreover, VORATRON™ GF series are designed to provide maximum processability efficiency with low squeeze force and optimized rheology the most demanding and efficiency assembly processes.

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.
