PET-coated aluminum wire typically refers to a material with aluminum wire as the base material, coated with a PET coating or formed into a composite structure through an aluminum plating process. It combines the conductivity and reflectivity of aluminum with the barrier properties and chemical resistance of PET. The following analysis focuses on its technical characteristics:

1. Aluminum Wire Base Material

Conductivity: Aluminum's conductivity is second only to copper, and it is less expensive, making it suitable for applications such as power transmission and electromagnetic shielding.

Reflectivity: Aluminum has a high reflectivity, making it suitable for reflective materials and optical devices.

Lightweight: With a density of only 2.7 g/cm, it is about 1/3 lighter than copper, making it suitable for weight-sensitive applications.

2. PET Coating/Painting

Barrier Properties: PET film effectively blocks oxygen and water vapor, extending product shelf life.

Chemical Resistance: It has good resistance to acids, alkalis, and organic solvents, protecting the aluminum base material from corrosion.

Heat Resistance: PET has a melting point of approximately 255℃. Aluminizing further enhances its heat resistance, making it suitable for high-temperature environments.

Surface energy regulation: Corona treatment and plasma treatment can increase the surface tension of PET and enhance its adhesion to aluminum.
