Norseal PF20 Series features enhanced micro-cellular polyurethane foam solutions, specifically developed for efficient functioning of batteries in a pack. PF25 is available in thickness as low as 1 mm, which aids in achieving higher energy density in a pack.
Uniformity of cell temperature and cell pressure is needed for a long battery life. The compressed foam between cells creates uniform pressure over the cell surface. The thermal insulation properties of the foam also help to maintain the cell face temperature. These properties and resulting function of the foam is very consistent over time and over a range of environmental conditions, ensuring a long life for the pack.
The key to performance is seen in the Compression Force Deflection (CFD) curve. Norseal PF cushion pads provide a flat CFD curve over a wide range of deflection, as shown here.
