Because PET material has the advantages of light weight, high strength, good transparency and gas resistance, non-toxic, odorless, etc., it has achieved rapid development. Since the 1990s, the production and application of plastic packaging materials have developed like mushrooms after rain. Later, with the maturity of touch technology, PET materials have naturally been used on various LCD screens, which is today's PET protective film!
The full name of PET is polyethylene terephthalate, which is composed of terephthalic acid and ethylene glycol
Made by alcohol condensation polymerization reaction.
Properties of PET protective film materials
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.
