Product Description of Polyethylene Terephthalate CAS#25038-59-9
Polyethylene Terephthalate (PET) resin is a high-performance polyester material widely used in packaging, films, and synthetic fibers. PET films offer excellent transparency, dimensional stability, mechanical strength, and abrasion resistance.
With good aging resistance, electrical insulation properties, and chemical stability against many organic solvents and inorganic acids, PET provides reliable performance across a broad temperature range. Its low energy consumption and good processability make it widely applied in plastic bottles, packaging films, LCD-related films, and various industrial applications.
