Application Of PET Protective Film Of Different Thickness

The PET protective film material is transparent and colorless, and the surface has been hardened. Generally, the surface hardening value of PET protective film materials is between 3H-4H depending on the place of production. The better the surface hardening, the stronger the wear resistance. Light transmittance is also the main property of PET protective film materials. Generally, the light transmittance is above 90%. The higher light transmittance not only allows us to have a good visual effect when using related instruments, but also has a good effect on the eyes. The protective effect.

Everyone knows that the use rate of PET protective film in the electronics industry is very high, and the thickness of the tape used in different applications is also different. The thickness of the PET protective film on the market now ranges from 30μm to 245μm. Now let’s analyze for everyone, what kind of properties do PET protective films of different thicknesses have, and in which areas are they mainly used?

30μm PET protective film

Although it is thin, it has good shear resistance and excellent bonding strength, good aging resistance and UV resistance, and has a low probability of fogging. It is generally used for LCDs and fixed nameplates.

50μm-60μm PET protective film

It is a thin and light variety, but it also maintains a good bonding effect. It is mainly used for the pasting of nameplates, earphone and microphone accessories, fixing of reflective film of digital camera, fixing of LCD reflector and backlight film group and the outer frame of the center button of mobile phone. .

80μm PET protective film

It has good bonding ability at normal temperature, suitable for smooth surface pasting on polar surfaces, fixing of LCD frame, digital camera buttons and hard materials, fixing of LCD front shell and panel.

100μm PET protective film

It has good adhesion strength to smooth surfaces, and is mainly used for fixing the LCD backlight film group and the bottom frame.

125μm PET protective film

The comprehensive performance is good, and it has good adhesion performance to most materials, and has excellent shear resistance and temperature resistance. It is mainly used for fixing windows and lenses, fixing LCD modules in digital cameras, and fixing between LCD backlight film group and bottom frame.

150μm PET protective film

It can maintain good adhesion at both high and low temperatures. It is suitable for EPDM sealing strips and has good anti-CaCO3 (calcium carbonate) performance.

160μm PET protective film

It not only has excellent shear strength, temperature resistance and bonding ability, but also can ensure reliable bonding effect under harsh external environment. Mainly used for fixing of mobile phone windows, lenses, batteries, digital camera rubber sheet memory cards, and fixing of battery boards.

200μm PET protective film

It has strong temperature resistance and is mainly used for fixing windows, lenses, batteries, digital camera rubber sheets, memory cards, and battery boards.

240μm PET protective film

Thicker material, high hardness, generally used in the industrial production of large pieces, suitable for fixing molds and decorative parts in furniture, fixing electronic load-bearing parts, and bonding to make cards. Generally, the thicker the material, the lower the cost
