PET Applications

1. Packaging Materials

• Food & Beverage Containers: Widely used for beverage bottles (carbonated drinks, mineral water), edible oil bottles, featuring high transparency, gas barrier properties, and food safety.

• Films & Packaging Boxes: Biaxially Oriented PET (BOPET) films for food, pharmaceutical packaging, and electronic protective films, offering tear resistance and chemical durability.

2. Fibers & Textiles

• Synthetic Fibers: PET is the main raw material for polyester, used in clothing, home textiles (curtains, bed sheets), industrial fabrics, and nonwovens with high strength, wrinkle resistance, and weatherability.

• Industrial Brush Filaments: Used in automatic car wash brushes, food cleaning equipment, and building cleaning tools, resistant to wear and chemical solvents.

3. Electronics & Electrical

• Engineering Plastic Components: Glass-fiber reinforced PET used for electronic device housings, connectors, and relays, meeting high rigidity, heat resistance (up to 120°C), and electrical insulation.

• Insulating Materials: PET films in capacitors, cable insulation, and motor insulation sheets ensure stability in high-frequency circuits.

4. Industrial Equipment & Machinery Parts

• Conveyor Belts: PET impregnated with TPU forms “impregnated fabric” for belt reinforcement, enhancing wear resistance and fatigue strength.

• Gears & Bearings: Modified PET gears used in automation equipment, resistant to moisture and with low friction coefficient.

5. Other Specialized Uses

• Medical Devices: PET used in surgical instrument packaging and disposable medical consumables, meeting sterility and biocompatibility standards.

• Optical Materials: High-purity PET films for LCD backlight modules and solar cell backplanes, with excellent light transmission and aging resistance.

PET’s application range is expanded via chemical modifications (copolymerization, reinforcement), and its recycling (e.g., rPET) supports circular economy development.
