Disadvantages of silicone protective film

Common quality problems of silicone protective film materials:
 

Crystal point is also a common quality problem of pet silicone protective film materials. Crystal point refers to the small pits on the surface of the protective film materials, which are also called bright spots. It is mainly common in three-layer pet silica gel protective film materials. The main reason is that silica gel is synthesized by using silica gel. Silica gel has fluidity. If the surface of the protective film material is squeezed by some small particles, crystal points will be formed. The best way to avoid crystal points is to protect the surface of the protective film.
 

Rainbow pattern is a common problem of pet silicone protective film materials now, because the surface of pet silicone protective film materials needs to be hardened, and hardening is to be processed at high temperature, so it will form a strip of color stripes on the surface of the material.
