Products detail&application
PI silicone adhesive tape offers exceptional high-temperature resistance and thermal stability, making it suitable for use in high-temperature zones. It is particularly emphasized for applications within lithium-ion battery cells. It is commonly employed for:
1.High-temperature protection in tab welding areas, preventing short circuits and abrasion of the tabs.
2.Encapsulation/wrapping of high-temperature regions on the cell body itself.
3.High-temperature masking during welding processes, protecting against splatter.
Oil-based adhesive PI tape delivers good high-temperature performance. While its heat resistance is generally inferior to silicone-based versions, it plays a vital role in areas requiring tolerance to moderate temperatures. Typical applications include:
1.Protection of the battery cell's side surfaces.
2.Insulation at the cell's top.
3.Securing BMS flexible printed circuits (FPCs).
