Self-Bonding Wire Enamels (SB)
Self-bonding enameled wire has a three-layer structure, consisting of an aluminum conductor layer, an insulation layer, and a self-adhesive layer.
When wound into coils, it can be bonded and shaped by heating or solvent treatment, making the coils tighter and more compact. It is widely used in the coating of instrument coils, voice coils, speakers, small motors, and sensors.
