US chemical manufacturer Huntsman has developed a new series of lightweight, durable polyurethane foam technologies designed for the potting and fixation of electric vehicle (EV) battery cells. Known as SHOKLESS foam systems, these products are intended to protect the structural integrity of EV batteries at the cell, module, or pack level from impact or thermal events. The product lineup includes a variety of low-to-high-density foams that can be utilized through common polyurethane dispensing processes, offering increased handling flexibility for manufacturers.
One of the key features of the new SHOKLESS foam systems is their moldable encapsulant version, which expands design and manufacturing possibilities for EV battery manufacturers and Original Equipment Manufacturers (OEMs). These systems are compatible with various manufacturing methods such as open- and closed-pour (injection) and cold-cure molding. Additionally, certain products in the range can be dispensed using high-pressure equipment. Huntsman provides simulation and modeling capabilities to assist customers in customizing and optimizing processing parameters, as well as the structural and thermal performance of the materials, to meet their specific requirements.
The SHOKLESS systems boast robust mechanical properties, offering good compression and tensile performance with high elongation to failure. Their elastic performance remains stable at different operating temperatures ranging from -35º to 80º C. Furthermore, these systems have been engineered to be user-friendly due to their low viscosity and ability to cure quickly at low temperatures. Huntsman emphasizes that these foam technologies provide reliable protection for EV battery cells while being easy to work with, ultimately enhancing the overall durability and performance of the battery systems.
With the ability to withstand impact and thermal events, the SHOKLESS foam systems play a crucial role in ensuring the longevity and safety of EV batteries. By providing a range of densities and moldable encapsulant options, Huntsman enables EV battery manufacturers and OEMs to tailor the foam materials to their specific requirements, enhancing the design and manufacturing processes. The compatibility with various manufacturing methods and the company’s simulation and modeling capabilities further support customers in optimizing the performance of the foam systems for their EV battery applications.
In conclusion, Huntsman’s new SHOKLESS foam technologies offer innovative solutions for potting and fixation of EV battery cells, addressing the need for lightweight, durable materials to enhance the safety and performance of these critical components. With a focus on mechanical robustness, temperature stability, and ease of use, these foam systems provide a reliable and flexible option for manufacturers looking to optimize their EV battery designs. By leveraging these advanced polyurethane foam technologies, EV battery manufacturers can create more resilient and efficient battery systems, contributing to the advancement of electric mobility and sustainability efforts in the automotive industry.
