Nowadays, with the development of the economy and society, the application of pet protective film has become more and more extensive.
The PET protective film is a high molecular organic compound with a special polyethylene (PE) plastic film as the base material. The material is transparent and colorless, and the surface is hardened. The hardening value of the surface of the PET protective film material is between 3H-4H- Good, the stronger the wear resistance.
In addition to abrasion resistance, light transmittance is also an important measure. When the light transmittance is above 90%, there will be a better visual effect, and the protection of the eyes will be better.
Now, the usage rate of PET protective film in the electronics industry is very high. However, it should be noted that the thickness of the tape in different use ranges is also different. The thickness of the PET protective film currently on the market generally ranges from 30 μm to 245 μm.
30μm PET protective film: It is the thinnest in terms of thickness, but it still has good shear resistance and adhesion strength, anti-aging performance and ultraviolet resistance are also very good, mostly used for LCD and fixed nameplate.
50μm-60μm PET protective film: It is a thin and light variety with good adhesion effect, which is mostly used for the attachment of nameplates, headphones and microphone accessories, as well as the fixing of the reflective film of digital cameras, between the LCD reflective film and the backlight film group and outside the center button of the mobile phone The fixation of the frame.
80μm PET protective film: good adhesion at room temperature, suitable for the bonding of smooth surfaces of polar surfaces and LCD frame fixing, digital camera buttons and hard materials, LCD front case and panel fixing, etc.
100μm PET protective film: good adhesion strength, mostly used for fixing between LCD backlight module and bottom frame.
125μm PET protective film: good overall performance, in addition to good adhesion performance, it also has excellent shear resistance and temperature resistance, and is mostly used for fixing windows and lenses.
150μm PET protective film: good adhesion at various temperatures, suitable for EPDM seals, and good calcium carbonate resistance.
160μm PET protective film: not only has excellent shear strength, temperature resistance and adhesion, but also has a good adhesion effect in harsh environments, and is mostly used for fixing mobile phone windows, lenses, batteries, etc.
200μm PET protective film: good temperature resistance, similar to 160 protective film.
240μm PET protective film: the material is thicker and the hardness is greater, which is mostly used in the industrial production of large parts.
