There are many types of protective films. According to the materials, there are pet acrylic protective film, pet silicone protective film. Acrylic adhesive and silicone protective film are mainly based on PET film (polyester), but the difference between them is very large. Next, coating online to introduce for you.
Differences between acrylic gel and silica gel protective film:
Acrylic protective film is widely used, and its viscosity is also high and low. It can be applied to a variety of products, and the price is relatively affordable.
Silica gel protective film is usually suitable for sticking to glass surface or mirror products. With automatic exhaust function, the high temperature and low temperature performance of protective film is better than that of acrylic protective film, but the price is slightly higher. Acrylic rubber protective film has the phenomenon of scraping powder with force, and there is glue residue when the customer's use requirements are high. Silica gel does not produce bubbles, but it is easy to produce ghosts.
Differences in performance:
At present, the pet protective film we use is generally with silica gel, and the application of silica gel is wider than that of acrylic adhesive. For example, the pet protective film that is widely used for screen pasting is mainly with silica gel, and the protective film of silica gel can bear higher temperature than acrylic adhesive. Acrylic protective film is usually used for packaging high gloss products and film switches. It is a cheap and simple film.
If we get a pet protective film product, how do we distinguish acrylic rubber protective film from silica gel protective film? The simplest way is to scrape the adhesive surface of the protective film with fingernails. If there is no glue and powder, it is silica gel, and vice versa, so we usually call silica gel powder free.
