With the popularity of the mobile phone film industry, protective film has become an important industry in a new era. PET protective film is used in both mobile phone screens and casings. PET protective film is divided into PET silicone protective film and PET acrylic protective film. Professionals in the industry can clearly distinguish between silicone and acrylic protective film, but for some customers who have not been in the protective film industry for a long time, sometimes they don’t really understand whether they need acrylic PET protective film or silicone. PET protective film. First, let’s first understand what is the difference in performance between acrylic protective film and silicone protective film? At present, most of the PET protective films we use are made of silica gel. The PET protective film of silica gel is more widely used than the PET protective film of the acrylic glue. For example, the PET protective film that is widely used in mobile phone screens is required to have silica gel. Moreover, the protective film of silica gel can withstand higher temperatures than acrylic glue. Acrylic protective film is mainly used for packaging high-gloss products and as a membrane switch. This is a cheap and easy-to-use film. When we get a protective film product, how do we distinguish between the acrylic protective film and the silicone protective film? The easiest and fastest way is to scrape the rubberized surface of the protective film by hand. The silicone rubber is not produced glue and powder, and the acrylic rubber is the opposite. Therefore, silica gel is also called powder-free glue. In addition, there are several differences between PET silicone protective film and PET acrylic protective film: 1. Acrylic adhesive is very sticky and will leave residual glue after tearing off, while silicone has relatively low stickiness, and there is no residual glue after tearing off. of. 2. Put the protective film on the surface of the object to be affixed, and use your finger to lightly tap it to quickly bond with no or less bubbles is silica gel, and the slow bonding and bubble generation is acrylic glue. 3. In terms of transparency, acrylic adhesive is better than silicone. 4. Silicone has good temperature resistance, easy to control the flatness of the rubber surface, and excellent low temperature performance. Acrylic glue is easy to process and produce, has good transparency, low price, good weather resistance, and strong viscosity.
