According to the scope of application, protective films can be applied in the following fields: metal product surface, coated metal product surface, plastic product surface, automotive product surface, electronic product surface, sign product surface, profile product surface, and other product surfaces.
Protective films can be divided into plastic protective film, digital product protective film, automotive protective film, household protective film, food preservation protective film, etc. However, with the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films, and their functions in the field of screen protective films are also varied, the earliest high-definition scratch-proof. From the earliest PP material to the popular AR material today, it has gone through more than 5 years of development and has been slowly accepted by the majority of mobile phone groups.
The development of silicone is based on acrylic glue, because in recent years, the demand for surface protection of 3C products has been increasing, and a large part of these applications have entered the so-called after-sales market, that is, in the store, and then DIY by consumers themselves. The application of this part emphasizes the exhaust performance of the use, so as to avoid the occurrence of bubbles during the film application process. Silicone meets the needs of this part of consumers. Silicone is mainly used for screen protectors produced on PET substrates. (Silicone adsorption is commonly used)
As the name suggests, the main raw material of rubber-based glue is rubber. It is mainly produced by European and specific Japanese protective film manufacturers. The main feature is that the product has a relatively large tolerance, that is, a product with a viscosity can be applied to product surfaces ranging from smooth to rough. Compared with the protective film of acrylic glue, the application range is much larger. Therefore, generally speaking, the viscosity of rubber-type protective films is only about four gears, while the protective film of acrylic glue must be classified as a product separately for about every 20g/25mm interval. Therefore, there are many varieties of acrylic glue protective films. For manufacturers' stocking, inventory, and application, rubber-type protective films are much simpler. The second advantage of rubber-type protective films is that because of their large tolerance, they can use protective films with higher viscosity, and are therefore particularly suitable for applications with complex post-processing, such as stainless steel plates, aluminum plates, etc. that require stamping.
