What are the differences between anti-static PET protective film and electrostatic film?

As we often say, anti-static PET protective film is generally divided into rubber surface anti-static, film surface anti-static, and double-sided anti-static; First of all, the anti-static rubber surface refers to the coating process of PET protective film, adding anti-static agent in the glue, in order to achieve the effect of anti-static rubber surface, the anti-static protective film cleanliness of the rubber surface will be relatively better.

The second film surface antistatic refers to the PET substrate surface coated with a layer of antistatic agent or direct use of antistatic PET substrate made of a protective film, film surface antistatic protective film generally in die cutting punching type can make the protective film between each other not because of static electricity and stick together;

The third double-sided antistatic refers to the combination of the first two ways to make a protective film, this protective film will have a certain shielding effect, and these several anti-static protective film can play a role in preventing electrostatic breakdown of the circuit board, so some electronic products screen surface will be used more.

Anti-static pet protective film and electrostatic film are two completely different things, first from the material, our common anti-static protective film is generally pet material protective film, and electrostatic film is generally pe material protective film; The second difference is that the anti-static pet protective film is coated with anti-static agent inside the glue or on the surface of the pet film, so that the pet protective film can prevent the electrostatic adsorption of dust and breakdown of the circuit board, while the PE electrostatic film is bonded to the surface of the paste by electrostatic adsorption, because it does not have adhesive itself. So there’s no risk of gum residue.

Many customers have asked us whether the pet protective film is adsorbed by static electricity. I have asked many of our friends about this question, and reached the same conclusion: No. The common materials of electrostatic film are PE, PVC and so on. But there may be a misunderstanding here. Customers regard the pet protective film that is slightly sticky and only a little sticky as an electrostatic film to use. The viscosity of the micro-mucosa is very low, and they even don’t feel it when they touch the rubber surface by hand. It’s just very low viscosity.
