A foam material designed for battery liner applications

The battery liner is usually a soft compressible material that can resolve compression changes without becoming too hard or soft as it expands or contracts so that the pressure on each soft-pack battery remains constant. Whether the batteries are individual soft pack batteries or multiple batteries in series, they must all be subjected to a constant stacking pressure, even when they are expanding. So how can constant force be maintained with a system in uniform motion? The answer is the use of battery liners.

Rogers Foam has a battery liner material designed to meet the challenges of electric/hybrid vehicle applications. the unique pore structure of PORON polyurethane foam material allows for consistent long-term performance and allows for die-cutting to create excellent battery liner products. In addition to its compact size, the material has excellent resistance to compression deformation, the ability of the material to spring back after being compressed, and the ability of the material to maintain a stable bounce when compressed.
