Knowledge Of PE Protective Film Quality, Transmittance, And Construction

The PE protective film is not firmly adhered to the middle of the maintained product, causing it to fall off during the entire process of transportation and use. The reason for these problems is exactly the opposite. The higher probability is that the viscosity of the polyurethane resin used in the manufacturing of the protective film product is insufficient, and there is also a possibility that the working pressure of the film pressing machine used by the customer during the molding process is insufficient, or the surface of the profile is not cleaned and tidy, Dust or spray paint can harm the actual effect of the adhesive. If this problem occurs, targeted treatment should be given to the cause. Replacing the adhesive can increase the working pressure of the glass film, or paying attention to reasonable and effective cleaning of the surface of the profile during the glass film process to prevent such problems from occurring.
After being used for a period of time, the protective film mainly performs well in the middle, but the wings on both sides rise. The primary factor causing this situation is that the stretching level of the protective film is relatively high during the entire adhesion process with the maintained profile. After being applied, there is excessive shrinkage in the high-temperature natural environment, which often occurs on products of users in southern regions, Therefore, during the production process of PE protective film, it is necessary to pay attention to the hazards of natural environmental temperature differences on product application, and avoid many unnecessary surface stretching during the entire adhesion process.
The issue of adhesive opening in protective film products is often reflected on the profile protective film. When the customer removes the protective film from the surface of the profile after the installation project is completed, the main adhesive manifestation of the protective film is not accompanied by the protective film, but rather remains on the profile product. This is also something the customer does not want to see. Due to this inconvenience, dedicated personnel must scrape this strong adhesive off the profile, Especially time-consuming and time-consuming, there are various probabilities of these problems occurring, and it is highly likely that the working pressure adhesive used for the protective film product does not meet the requirements or is too sticky, resulting in the external support force exceeding the thermal stress when the PE protective film product is peeled off and remaining on the profile.
The PE protective film adopts an effective three-layer structure with a frosted surface layer, which can effectively prevent fingerprint invasion when used. Generally, fingers slide without leaving any marks, even if there are liquid residues such as sweat, it can be cleaned by gently wiping the hand, greatly ensuring the visual effect of the screen. The material is treated with special techniques, which can effectively prevent light reflection and reduce the problem of sunlight and screen reflection.
The material of PE protective film has higher transmittance, and as a material for LCD screen protective film, it has no visual barriers, has impact strength, good mechanical properties, and impact strength is 3-5 times better than other materials. It is resistant to oil stains, dilute acids, dilute alkalis, and other solvents.
PE protective film has good weather resistance, can withstand low temperatures of -70 degrees Celsius at low temperatures, and can withstand temperatures up to 150 degrees Celsius at high temperatures. It prevents water vapor penetration, has good water vapor blocking function, strong protective performance, is an environmentally friendly material, non-toxic and pollution-free, and is truly a safe material.
