Class 240 Aromatic Polyimide Tape Covered Bare square Copper Magnet Wire

Insulation MaterialThe insulation material shall be an aromatic polyimide tape with an adhesive layer on one or both sides to bond the insulation to the exposed conductor. The covering shall be one or two strips of tape wrapped spirally around the wire. After wrapping, the tape shall be heat sealed.

Characteristic:

Adhesion and flexibility:No loss of adhesion between tape and conductor or between tape layers
SpringbackNot more than 5.5°
Dielectric breakdownNot less than 1000 V/mil (39370 V/mm) of the smallest thickness on one side of the tape cover (half the minimum increase)
