Enamel wire has excellent chemical resistance, including solvent resistance and direct solderability.
(1) Solvent resistance, generally, enameled wire needs to undergo a dipping process after being wound into coils. The solvent in the dipping varnish has varying degrees of swelling effect on the varnish film, which is more pronounced at higher temperatures. The chemical resistance of the enameled wire's varnish film mainly depends on the inherent properties of the varnish film itself. Under certain conditions of the varnish material, the enameled wire process also has a certain impact on the wire's solvent resistance.
(2) The direct welding performance of enameled wire, reflecting the wire's ability to weld solder without removing the enamel coating during winding processing. The main factors affecting direct welding performance are: the influence of the process; the influence of the enamel material.
For thicker enameled wire, you can use a knife or a hacksaw blade to peel off the enamel layer one by one. When scraping, do not just scrape both sides; carefully scrape along the circumference, ensuring not to damage the wire. This method is called the scraping enamel removal technique.
For finer enameled copper wire, scraping to remove the enamel can break the wire. Instead, using the fire burning method is recommended.

Dongguan Xinmao Electrical Materials Co., Ltd. is a professional manufacturer engaged in the production and processing of multi-strand enameled wire, braided enameled wire, earphone enameled wire, transformer multi-strand enameled wire, and enameled braided wire, with a complete and scientific quality management system.
High-temperature coated wire is unafraid of extreme heat. With the continuous development of science and technology, higher requirements are placed on electronic and electrical equipment. For commonly used motors, as the rotor continuously rotates and the current flows continuously through the windings, a large amount of heat is generated inside the motor. Therefore, it is required that the insulating material within the windings has excellent high-temperature and aging resistance to ensure the normal operation of the motor. As a high-quality electrical insulating coating, the quality of high-temperature coated wire directly affects the economic and technical indicators and service life of electrical equipment. It can face high temperatures without fear.
