White PET coated wire is coated with white polyethylene terephthalate. Combining the excellent properties of PET with the electrical conductivity of wire, it excels in electrical insulation, marking, and weather resistance. It is widely used in the electronics, automotive, and communications sectors. The following are the unique advantages of white PET coated wire:

1. Electrical Insulation

PET is a polar polymer with excellent electrical insulation properties, maintaining stable performance even at high frequencies. However, its corona resistance is poor, making it unsuitable for high-voltage insulation. Its high dielectric strength effectively isolates conductors, preventing leakage and short circuits.

2. Mechanical Properties

High Strength: PET film has a tensile strength comparable to aluminum foil, nine times that of HDPE film, and three times that of PC and PA films. Reinforced PET exhibits low creep and excellent fatigue resistance.

Dimensional Stability: Dimensional change is minimal over a wide temperature range (-70°C to 120°C), making it suitable for precision electronic equipment.

Abrasion Resistance: The surface coating resists friction and scratches, extending the life of the wire. 3. Weather Resistance and Chemical Stability

Heat Resistance: Long-term operating temperature reaches 120°C, and can withstand higher temperatures for short periods.

Corrosion Resistance: Resistant to oils, weak acids, and organic solvents, suitable for use in complex environments.

Flame Retardancy: Select models are certified V0 flame retardant, meeting safety standards.

4. Appearance and Marking

White coating: Provides high-contrast marking for easy line identification and management, suitable for applications requiring clear marking, such as data centers and industrial control systems.

Smooth Surface: Reduces dust absorption, keeping lines clean.
