POLYURETHANE ENAMELED COPPER WIRE SOLDERABLE UEW SELF BONDING WIRE
A special type of enamelled wire is self bonding wire. Self bonding wire is an enamelled wire with an additional adhesive enamel overcoat. This adhesive has a bonding feature, which is activated by heat or solvents. Once activated the adhesive bonds turn to turn windings into a compact self supporting coil. The use of self bonding wire may offer cost and manufacturing advantages in some winding applications as bobbins, tape, varnishing, or impregnation may be eliminated.Self bonding wire can be supplied with different conductor materials such as self bonding copper clad aluminum wire, self bonding aluminum wire etc.
