US chemical manufacturer Huntsman has developed a series of new lightweight, durable polyurethane foam technologies for the potting and fixation of EV battery cells.
The new SHOKLESS foam systems can help to protect the structural integrity of EV batteries at a cell, module, or pack level from impact or a thermal event. The product portfolio includes a range of low-to-high-density foams that can be used via common polyurethane dispensing processes for extra handling flexibility.
A moldable encapsulant version can further expand design and manufacturing options for EV battery manufacturers and OEMs.
SHOKLESS systems are designed to be compatible with a number of different manufacturing methods such as open- and closed-pour (injection) and cold-cure molding. Certain products in the range can also be dispensed with high-pressure equipment. Huntsman provides simulation and modeling capabilities that can help customers customize and optimize processing parameters, as well as the structural and thermal performance of the materials, to meet their needs.
“With robust mechanical properties, the new SHOKLESS systems can offer good compression and tensile performance with high elongation to failure. Elastic performance can remain stable at different operating temperatures ranging from -35º to 80º C. The new systems have also been developed to be easy to work with thanks to their low viscosity and ability to cure quickly at low temperatures,” the company said.
