PVC material protection paste is characterized by its own soft texture, and easy to paste, but the material is thicker, the transmittance is not good, so that the screen looks more hazy. It also leaves a mark on the screen for glue. This material at the same time also relatively easy to change with the temperature of the yellow oil, the service life is relatively short. (The market can not see the basic) PVC modified version of the protective film to solve the previous heavy and light transmission of the problem. But still not solve the problem of easy to turn yellow out of the oil, and PVC this material does not have the ability to resist scraping.
