Chemical structure of PET protective film material:
PET is polyethylene terephthalate in the whole process, which is made by the condensation polymerization of terephthalic acid and ethylene glycol.
The nature of PET protective film material
The PET protective film material is transparent and colorless, and the surface has been hardened. According to the information provided by Enjue Protective Film Material Co., Ltd., general PET protective film materials have different surface hardening values between 3H-4H, and the surface is hardened. The better, the stronger its wear resistance. Light transmittance is also the main property of PET protective film materials. Generally, the light transmittance is above 90%. The high light transmittance not only makes us have a good visual effect when using related instruments, but also has a good effect on the eyes. The protective film effect.
Types of PET protective film materials
High permeability, frosted, diamond, anti-peep, anti-radiation, anti-fingerprint, mirror and other PET protective film materials. It is reported that a 3D naked eye protective film material is currently being developed, mainly to have 3D effects when watching 3D movies!
Common quality problems of PET protective film materials
The rainbow pattern is a problem often encountered in PET protective film materials, because the surface of the PET protective film material has to be hardened, and the hardening has to be processed at a high temperature, so color stripes will be formed on the surface of the material
