PC Insulating Flame Retardant Film

PC insulating flame retardant film is widely used in new energy battery cell separator film.While what's the cell seperator film?The battery cells in our common parlance refer to the basic constituent units of new energy power battery packs. A complete power battery pack is composed of several lithium battery cells. In the structure of lithium battery cells, the separator is one of the important components. It is attached to the positive and negative electrodes of each cell and plays the roles of insulation shielding, flame retardancy and protection. The main body of the separator is PC insulating flame retardant film, 3M adhesive, and release paper are adhered to the back adhesive surface of the main body, and then formed through embossing and die-cutting processes.

The main body of the cell separator is a PC insulating flame-retardant film. 3M adhesive, release paper are adhered to the back adhesive surface of the main body. After embossing and die-cutting processes, it is formed.

 

 

The PC insulation flame-retardant film possesses excellent flame-retardant properties, high voltage resistance, low water absorption rate, good bending resistance, tear resistance, non-breakability, stable size, etc. At the same time, it has good heat resistance and low-temperature resistance, and maintains stable mechanical properties within a wide temperature range. At room temperature, it can achieve a Z-direction bulging height of 3mm. It can be applied to battery modules, cells, PACKs, etc. of new energy vehicles.

 

Under the circumstances where market demands undergo drastic changes, relying on our long-term industry expertise and the advantage of continuous innovation, we ensure that our new products can adapt to market demands. Currently, our PC insulating flame retardant film has been widely applied in the mainstream lithium battery manufacturing enterprises in China due to its excellent flame-retardant and tensile properties. Besides the field of new energy vehicles, with the extensive application of lithium batteries in energy storage and electronic products, PC insulating flame-retardant film will have a broader application prospect in the future.
