Which is better between PE separator and PET separator?

The PE separator is a microporous and porous film, mainly made of PE, which is placed between the positive and negative electrodes inside the cell. Main function: isolate the positive and negative plates, prevent the short circuit of the cathode and anode inside the battery, allow ions to pass through, and have the function of maintaining the electrolyte. In fact, in addition to pp and PE isolation films, there is also a type of PET isolation film. So, which is better between PE isolation film and PET isolation film?

PE is a macromolecular organic compound with a simple structure, which is widely used in the world today as a macromolecular material. PE isolation film is based on special polyethylene plastic film, which is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities. PET release film manufacturers remind that the advantage of PE release film is that the protected product will not be polluted, corroded, scratched during production, processing, transportation, storage and use, and protect the original smooth and shiny surface, thereby improving the product's quality. quality and market competitiveness.

PET isolation film, also known as film high temperature resistant polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields.
