by:SYJ     2021-07-20

PET material has the advantages of light weight, high strength, light transmission and good temper, non-toxic, odorless, etc. In the LCD protective film manufacturing industry, electrostatic adsorption is mainly used, instead of OCA electronic optical glue. The key application is in industrial production, and also appeared in various LCD protective film industries in the middle and late stages. Among them, the sales market for high temperature resistant PET protective film is very large. The protective film produced by some manufacturers to control costs is far from reaching the temperature that customers must withstand. How do you know whether the PET protective film is high temperature resistant? Let’s take a look at it.

The heat resistance of PET protective film can generally be between 120 degrees and 260 degrees. It is commonly used in various art paintings, painting leather processing plants, spray coatings and electronic parts manufacturing. Maintenance function of circuit board and high temperature solution. So how do you identify fake high-temperature protective films? The identification can be carried out from the following aspects: 1. Taste; 2. Appearance; 3. Residue after ignition; 4. Specific high temperature detection, over 260 ° high temperature, check whether there are glue marks, shrinkage, etc. .
