With the popular application of protective film, screen protection film as well as high-frequency protective film and other intelligent product decorations have also been developed rapidly accordingly, especially high-frequency protective film is very important to people. High-frequency protective film is one of the many protective films, is a special polyethylene (PE) plastic film as the base material of the simplest polymer organic compounds.


We all know that the use rate of high-frequency protective film in the electronics industry is very high, and the thickness of the tape used for different uses varies, and the thickness of high-frequency protective film in the market now ranges from 30μm to 245μm. Now, we will analyze what kind of properties the different thicknesses of high-frequency protective film have, and in which fields they are mainly used.


30μm high-frequency protective film: Although thin, it has good shear force and excellent adhesive strength, anti-aging performance and UV resistance are very good, the probability of fogging is very low, generally used for LCD and fixed nameplate, etc.


50μm-60μm high-frequency protective film: through the thin varieties, but also maintain a good bonding effect, mainly used for nameplates, headset microphone attachment paste, digital camera reflective film fixing, LCD reflective film and backlight film group and cell phone center button frame of the fixed.





80μm high-frequency protective film: good adhesive ability at room temperature, suitable for polar surface smooth surface paste, LCD frame fixing, digital camera button and hard material, LCD front case and panel fixing.


100μm high-frequency protective film: good adhesive strength to smooth surface, mainly used for fixing between LCD backlight film group and bottom frame.


125μm high-frequency protective film: good overall performance, good adhesion to most materials, and excellent shear resistance, temperature resistance. It is mainly used for fixing windows and lenses, fixing LCD modules in digital cameras, and fixing between LCD backlight film sets and bottom frames.


150μm high-frequency protective film: can maintain good adhesion at both high and low temperatures, suitable for EPDM sealing strips, good resistance to CaCO3 (calcium carbonate) performance.


160μm high-frequency protective film: not only has excellent shear strength, temperature resistance and adhesive ability, but also can ensure reliable adhesive effect under harsh external environment. It is mainly used for fixing the window, lens and battery of cell phone, rubber film of digital camera and battery plate.


200μm high-frequency protective film: excellent temperature resistance, mainly used for window, lens, battery fixing, digital camera rubber sheet, memory card, battery plate fixing.


240μm high-frequency protective film: thicker material, hardness, generally used in the industrial production of large pieces, applicable to the furniture in the mold and decorative parts of the fixed and electronic weight parts of the fixed, as well as bonding made of card, generally the thicker the lower the cost.
