Nowadays, the market economy is developing rapidly, and people's requirements for all aspects of products are constantly improving. Pe steel mirror protective film has more and more functions, and the product specifications are different. Its biggest advantage is that it can protect steel mirror products from pollution, corrosion, scratches and maintenance during processing, transportation, storage and use. The bright and shiny surface then improves the quality of the product and market competitiveness.
According to the requirements of use, the Pe steel mirror protective film should have good adhesion and easy to peel. Moreover, it should have a long storage period and be stored in the warehouse for more than one year without any change in quality. In addition, the peeling force should be kept stable, and the change over time is small, that is, the smaller the peeling force is, the better. In addition, it should have excellent mechanical properties, meet the user's requirements for tensile strength, elastic modulus, elongation and so on.
The viscosity of Pe steel mirror protective film is often affected by some factors. One of the main factors is the wettability. The pressure sensitive adhesive can only have a good wettability to the surface of the bonded object to a certain extent. Realize its close contact and create conditional molecules for the combination of physics and chemistry. Followed by the movement and diffusion, the pressure-sensitive adhesive molecules of the PE protective film will effectively move to the surface of the material to be bonded. When the distance bond between the two is less than 5A, a physical-chemical bond will occur.
