Properties 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. In the current market, Japan's PET protective film materials are relatively excellent, followed by Taiwan and South Korea again.
Types of PET protective film materials
When the author did research in Enjue Protective Film Material Company, the staff of the company showed me: PET protective film materials such as high permeability, frosted, diamond, anti-peep, anti-radiation, anti-fingerprint, mirror. It is reported that a 3D naked eye protective film material is currently being developed, mainly to have 3D effects when watching 3D movies!
