Non-flammable foam that absorbs cell swelling and blocks thermal propagation.
Silicone foam is the battery's shock absorber and firewall in one. It cushions the contraction and expansion of cells during charge and discharge, while its self-extinguishing structure prevents heat from one cell igniting the next. The TF/TP/TH series covers ultra-soft cushioning through firm cellular grades for top covers, compression pads and end plates.
