The protective film has become a very critical industrial chain in the new era, especially in the mobile phone protective film, PET protective film is used for mobile phone screens and cases. PET protective film is divided into PET silicone protective film and PET acrylic protective film. Professionals can clearly divide the silicone protective film and acrylic protective film, but for some people who have not been in the protective film field for a long time, it is difficult to distinguish. Some customers even don't understand whether they need acrylic protective film or silicone protective film.
When we get PET protective film goods, how to distinguish between acrylic protective film and silicone protective film?
1、A very simple and convenient way is to scratch the adhesive surface of the protective film with your fingernails. Silicone protective film is not a film that causes glue and powder, and acrylic protective film will cause white powder and glue. Because of this effect, silicone protective film is also known as powder-free glue;
2、Difference in taste: Silicone protective film is colorless and tasteless, while acrylic is the opposite.
3、After ignition, the silicone protective film turns gray and the acrylic protective film is liquid.
In addition, PET silicone protective film and PET acrylic protective film has the following differences:
1、Acrylic glue has low viscosity, strong glue will remain after the adhesive is detached, and the viscosity of silica gel is low.
2、Put the protective film on the surface of the object to be adhered, and then use your fingers to slowly touch it quickly. The bubble is basically free or less silicone protective film. Acrylic adhesive is slow.
3、In terms of clarity, acrylic is better than silica gel.
4、Silicone has excellent temperature resistance, easy to control the flatness of the glue surface, and has excellent ultra-low temperature characteristics. Acrylic glue is easy to manufacture and process, with good clarity, low price, good aging resistance and high viscosity.
