Black PET coated wires typically refer to wire products that use PET as the insulation or sheathing material, with the conductor made of tin-plated copper or similar materials, and are entirely black in appearance. The following is a detailed introduction to their material characteristics:

1. PET Substrate: PET is a thermoplastic polyester material with high strength, chemical resistance, high transparency, and excellent barrier properties. As an insulation or sheathing material in wires, it effectively protects the conductor, preventing current leakage and damage from the external environment.

2. Black Coating: The black coating may be achieved by adding pigments such as carbon black. This not only gives the wire an aesthetically pleasing appearance but may also enhance its light and weather resistance, extending its service life. Simultaneously, the black coating helps absorb heat, improving the wire's heat resistance.

3. Conductor Material: The conductor is usually made of tin-plated copper or similar materials, possessing good conductivity and corrosion resistance. Tin plating prevents oxidation of the copper conductor, improving the reliability and stability of the wire.
