Saint-Gobain battery pack compressions pad options include silicone and micro-cellular polyurethane foams. These expansion pads, also referred to as cushion or pressure pads, feature a range of densities and thicknesses, different levels of tackiness and flame retardancy from UL94 HBF to V-0. Utilizing a foam solution accommodates:
Silicone Foam Rubber
- expansion/contraction of cells by providing consistent deflection force over a wider range of compression and temperature
- electrically insulating to minimize/prevent arcing within module
Norseal F-12 and F-20 are soft, lightweight silicone foams that provide excellent flame resistance with low toxicity and smoke generation, meeting the highest flame rating of UL94 V-0. Norseal F-12 has a modified cell structure and low density and Norseal F-20 has a finer closed cell structure with a medium density.
Micro-cellular Polyurethane Foam
Norseal PF series is comprised of closed-cell microcellular foams that have low compression set. Their excellent resiliency is maintained within a narrow range, over a range of temperatures and compression forces. They also meet the flame performance per ASTM D4986 (equivalent to UL94 HBF). The PF20 Series has the added advantage of being available in thicknesses as low as 1mm and density as low as 200Kg/m3. Norseal PF100 Series, our most recent development, provides the flattest CFD curve over the widest workable compressive strain.
