PET is a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface.
It has excellent physical and mechanical properties over a wide temperature range, with a long-term use temperature of up to 120 ℃. It has excellent electrical insulation, and even at high temperatures and frequencies, its electrical performance is still good. However, it has poor corona resistance, creep resistance, fatigue resistance, friction resistance, and dimensional stability.
Advantages of PET as a packaging material:
① It has good mechanical properties, with an impact strength 3-5 times that of other films, and good bending resistance.
② Resistant to oil, fat, dilute acids, alkalis, and most solvents.
③ It has excellent resistance to high and low temperatures, and can be used for a long time within the temperature range of 120 ℃. It can withstand high temperatures of 150 ℃ and low temperatures of -70 ℃ for short-term use, and has little impact on its mechanical properties at high and low temperatures.④ The permeability of gas and water vapor is low, and it has excellent resistance to gas, water, oil, and odor.
⑤ High transparency, can block ultraviolet rays, and has good glossiness.
⑥ Non toxic, odorless, with good hygiene and safety, it can be directly used for food packaging.
Glass fiber reinforced flame retardant PET is a new type of modified engineering plastic with excellent comprehensive properties, and it is also the fastest growing engineering plastic among the world's general engineering plastics in recent years. The product has the characteristics of high rigidity, high toughness, good fatigue resistance, heat resistance and performance, low water absorption, flame retardancy, chemical resistance, and excellent electrical performance. Enhanced flame retardant PET has excellent molding, good dimensional stability, and high surface finish, making it suitable for manufacturing various thin-walled and complex shaped products.
