The base material of the blue PET protective film is PET material, one side of the PET material is coated with special acrylic pressure-sensitive glue, the peeling force is 9N/25MM, the tensile strength is 140N/25MM, the elongation of the material is 80%, and the protective film is resistant to temperature Up to 150 degrees. After temporarily fixing the adhered surface, peel off the protective film without leaving any adhesive residue, and it has been widely installed by home appliance manufacturers.
Details of the characteristics of the blue pet protective film
Regarding the protective film, we need to know and understand it, not only to master its knowledge, but also to learn and grasp some problems. In this way, it is comprehensive and specific, and will not be missed. So, on the basis of this requirement, let's continue to study. How to choose the unit for the viscosity of the protective film?
The acrylic protective film in the protective film is also a kind of protective film, so in order to let everyone get new gains, it needs to be recognized and understood. If the understanding of the protective film increases, it can actually be used correctly and reasonably. Description of the use and inspection items of acrylic protective film
If you want to judge whether the glue in the PET protective film is good or bad, you can conduct a high-low temperature alternating damp heat test. If the test fails, it means that the glue has poor weather resistance, which in turn means that the quality of the glue is poor. Because this cannot use PET protective film, it needs to be adjusted. If it is not adjusted, only replace it.
How to judge the glue of PET protective film?
The 5 wire in the protective film industry refers to 0.5mm, or 50 microns. Because, in the protective film industry, it is customary to express it in silk or microns. Therefore, everyone should be very clear. And, in order not to cause unnecessary problems and troubles, do not make a mistake. In the protective film industry, what does 5 silk mean?
The reason for the sound during peeling is that the release force is too large, followed by the result of uneven coating. In view of the above problems, the release film generates static electricity during the winding process, and the solution to absorb dust is more common. The release film has low release force, and the release layer feels easy to peel off. After a period of time, the tape and release film will not peel off. Reverse peel means that the peeled material has not peeled off.
The problem of degumming of PET protective film often occurs on the profile protective film. When the user peels off the protective film from the surface of the profile after finishing the construction of the profile device, the case where the protective film does not adhere to the protective film remains on the profile product. This is something users don't want to see. Someone who cuts these glues out of the profiles is needed because of the labor involved. Especially if it takes a lot of effort, there are many possibilities for this problem. The pressure paste used for the protective film product does not meet the requirements, and there is too much adhesion. When the PE protective film product is peeled off, the external tension is greater than the internal negative force, and the possibility of remaining on the profile high. If the user encounters such a problem, please apply a small amount of alcohol on a clean rag and try to wipe off the remaining sensitizer until the sensitizer becomes clean. However, be careful not to use too much force when wiping. Otherwise, the finish of profile products may be affected.
