Providing Efficient Battery Function with Polyurethane Foams

Norseal® PF40 Series from Saint-Gobain Tape Solutions features improved micro-cellular polyurethane foam solutions, designed specifically for the efficient operation of batteries in a pack. PF45 and PF47 are available in this series in thicknesses up to 10mm, thanks to work on a number of EV projects of varying designs and functional requirements.

For long battery life, uniformity of cell pressure and cell temperature is crucial. The compressed foam between cells builds even pressure over the cell surface.

In addition, the foam’s thermal insulation properties help in maintaining the cell face temperature. These properties and resulting function of the foam are highly steady over time and across different environmental settings, thus guaranteeing an extended service life for the battery pack.
