Among the many properties of the protective film (viscosity, thickness, color, stretchability, light transmittance, etc.), one is called weather resistance. As the name implies, it is resistant to environmental climate, so why should the protective film emphasize this property? Does the weatherability affect the quality of the protective film?
During the use of the protective film, the finished product protected will also be directly exposed to the sun, and the time may be as long as half a year to one year. In this process, the protective film is generally not contaminated, but the performance may be affected. Changed. You even need to be stuffed in a container and travel across the sea for months. The environment encountered by the protective film is actually quite harsh.
The protective film has excellent mechanical functions, and when used, it is very suitable for the tensile strength, elastic modulus, elongation, etc. of its users. The protective film is lazy to the appearance of the material being maintained, and has an excellent adhesion function to the material being maintained. During the data transfer and processing, the maintenance film will not rise and fall.
The protective film has good weather resistance and sticky stability. After several days or a long time, the peeling force does not increase significantly, and it is easy to peel off. When it is peeled off, there is no residual glue on the protected surface and no shadow.
The protective film will perform well in the center in the future, but its two ends are tilted. The main reason for this phenomenon is that the protective mold stretches a lot during the process of maintaining the profile. In the future, High temperature environment, showing unnecessary shrinkage.
The problem of protective film mostly occurs in the south, so the protective film should pay attention to the impact of environmental temperature differences on the use of the product after the production process, and avoid unnecessary appearance stretching during the film bonding process.
