The PET protective film is coated with its polymer conductive polymer in the process of production. The surface resistivity of the product is low and the performance is relatively stable. The chemical resistance of the product is good, and it can be attacked by chemical substances to a certain extent.
The PET protective film is not affected by the environment such as air when it is used, so the product is very suitable for use in packaging materials and has better barrier properties against oxygen and water vapor. Excellent thermoforming performance, comparable to PVC sheet, can be used for vacuum forming of PET hot molded products.
PET protective film has excellent transparency and smoothness, excellent surface decoration performance, can be printed without surface treatment, and can be easily pressed into a pattern.
The PET protective film material is transparent and colorless, and the surface is hardened. Generally, the PET protective film material has a hardening value of 3H-4H depending on the place of production. The better the surface hardening, the stronger the wear resistance. Light transmittance is also the main property of PET protective film material. 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 eye. Protection.
