Swelling Tape-POB05A3
Swelling Tape for Battery
Our lithium battery swelling tape is a next-generation functional insulation tape based on modified TPU / PVDF substrate, coated with electrolyte-resistant pressure-sensitive adhesive. Unlike conventional OPS expansion tape which only expands in thickness and tends to shrink at high temperatures, this tape delivers 3D isotropic swelling (length, width and thickness) once contacting electrolyte. It fills the gap between the winding cell and steel shell, secures the cell firmly, suppresses internal shaking under vibration, and protects the tab welding zone against short-circuit risks. It is widely adopted for high-rate, full-tab cylindrical cells for power tools, energy storage and automotive-grade battery applications.
