What is self bonding enamelled copper wire?

January 12, 2024

Self-bonding enameled copper wire is a vital component in various industries, offering unique features that make it a preferred choice for many applications. Ruiyuan company is a leading producer of self-bonding enameled wire, including alcohol-type self-adhesive enameled wire and hot-air type self-adhesive enameled wire. But what exactly is self-bonding enameled copper wire, and how does it differ from traditional enameled wire?


Self-bonding enameled copper wire, also known as self-adhesive enameled wire, is a type of wire that has a special adhesive layer applied to the enamel coating. This adhesive layer allows the wire to bond to itself when it is wound into coils, eliminating the need for additional bonding agents or materials. This feature makes self-bonding enameled wire particularly well-suited for applications where space is limited, as it eliminates the need for extra adhesives or insulation. Additionally, the self-bonding feature helps to improve the overall mechanical and electrical properties of the wire, making it a reliable choice for various uses.


Ruiyuan company produces two main types of self-adhesive enameled wire: alcohol-type and hot-air type. The alcohol self-adhesive enameled wire is coated with a special adhesive that activates when exposed to alcohol, allowing for easy bonding of the wire without the need for additional heat. On the other hand, the hot wind self-adhesive enameled wire requires the application of heat to activate the adhesive, providing a more durable and long-lasting bond. The choice between these two types depends on the specific requirements of the application, with alcohol self bonding wire being suitable for simpler bonding needs and hot wind self bonding wire being more suitable for high-temperature applications.


Self-bonding enameled copper wire is used in a wide range of industries, including the electronics, automotive, and aerospace sectors. Its unique self-bonding feature makes it particularly useful in applications where space is limited, such as in small motors, transformers, and solenoids. The adhesive layer also provides additional protection and insulation, making it ideal for use in harsh environmental conditions. Overall, self-bonding enameled wire offers significant advantages in terms of space-saving, reliability, and performance, making it a top choice for many engineering and manufacturing applications.
