PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good friction and dimensional stability, low wear and hardness, high toughness in thermoplastics, good electrical insulation, little influence by temperature but poor corona resistance. Non-toxic, weather resistance, good chemical stability, low water absorption, resistance to weak acids and organic solvents.
