· Product description:
| Substrate: Polyester film Adhesive system: rubber adhesive Color: Coffee Specifications:(20/22/18mm) width (100M) length |
![]() |
· Product characteristics:
The use of customized ultra-thin green polyester film substrate resistant to electrolyte erosion has fundamentally solved the problem that the colored adhesive layer is easy to fade and change color. With the use of functional rubber adhesive, the electrolyte resistance of the adhesive tape is greatly improved, the adhesive force is long-term and stable, and it has excellent lithium precipitation prevention function. It provides a reliable guarantee for improving the cycle charge and discharge life of the battery and safe operation;
