The protective film can be divided into: plastic protective film, digital product protective film, automobile protective film, household protective film, food preservation protective film and the like. However, with the popularity of digital products such as mobile phones in China, the protective film has gradually become a general term for screen protectors, and its functions in the field of screen protectors are also varied, the earliest high-definition scratch-resistant. From the earliest PP materials to the popular AR materials, the materials have experienced more than five years of development and are slowly accepted by the majority of mobile phone groups.
The development of silica gel has been developed on the basis of acrylic glue, because the surface protection demand for 3C products has been increasing in recent years, and a large part of these applications have entered the so-called after-sales market, that is, in the market, and then by consumption. DIY yourself. The application of this part, with particular emphasis on the use of venting, in order to avoid the occurrence of bubbles in the process of filming, and silica gel meets the needs of this part of the consumer, silica gel is used in the production of PET substrate The curtain protects the main. (commonly used for silica gel adsorption)
As the name suggests, the rubber-based glue is mainly made of rubber. It is mainly produced by European and specific Japanese protective film manufacturers. The main feature is that the product is more tolerant, that is, a product with a viscosity can be applied. The surface is smooth to rough, and the application range is much larger than that of the acrylic glue. Therefore, in general, the rubber type protective film has a viscosity of only about four steps, and the acrylic glue protective film is about 20 g per interval. 25mm must be classified separately as a product, so there are many kinds of protective films for acrylic glue. For the manufacturer's stocking, inventory, and application, the rubber type protective film is much simpler. The second benefit of the rubber type protective film is also because of its high tolerance, so that a higher viscosity protective film can be used, and therefore it is particularly suitable for applications in which post-processing is complicated, such as stainless steel sheets, aluminum sheets, and the like.
