Among the many performance attributes of glass protective film, such as viscosity, thickness, color, stretchability, and light transmittance, one is weather resistance, which, as the name implies, is the ability to withstand environmental climate. In the process of using the glass protective film, the protected product will also be directly exposed to the sun. The time may be as long as half a year to a year. In such a process, the glass protective film will generally not be stained, but the performance may be There will be changes.
The glass protective film has excellent mechanical functions, and meets the requirements of its users with mild tensile strength, elastic modulus, elongation, etc. when used. The protective film is lazy to the appearance of the material to be maintained, and has an outstanding adhesion function to the material to be maintained. During data transfer and processing, the protective film will not warp or fall.
The glass protective film has good weather resistance and adhesive strength stability. After several days or long pasting, the peeling force does not increase significantly, and it is easy to remove. When removed, there is no residual glue on the protected surface and no shadows. After a period of use, the performance is still very good, but its two ends are tilted. The reason for this phenomenon is that the glass protective film stretches to a large extent during the post process of the maintained profile. After the post is completed, it will encounter high temperature environment. , Showing unnecessary retraction.
This problem of glass protective film mostly occurs in the south. Therefore, during the production process of protective film, attention should be paid to the influence of environmental temperature difference on product use, and unnecessary external stretching should be avoided during the filming process.
