Silicone PET protective film

The PET protective film material is transparent and colorless, and the surface has undergone hardening treatment. Generally, the surface hardening value of PET protective film materials varies from 3H to 4H depending on the origin. The better the surface hardening, the stronger its wear resistance. The transmittance is also a major property of PET protective film materials, with a general transmittance of over 90%. A high transmittance not only provides a good visual effect when using related instruments, but also has a good protective effect on the eyes.
