Polyethylene terephthalate resin, or PET, is used as the outer film for LCD tablets. PET polyester film is widely used in a wide range of fields due to its dimensional stability and high transparency. PET (polyethylene terephthalate) maintains excellent physical and mechanical properties over a wide temperature range, exhibits excellent fatigue and abrasion resistance, and exhibits excellent aging resistance. It also possesses outstanding electrical insulation properties and is stable to most organic solvents and inorganic acids. Furthermore, it boasts low energy consumption and excellent processability. Consequently, it has been widely used in plastic packaging bottles, films, and synthetic fibers.
