Product Details

This polyimide tape is manufactured from commercial, heavy grade Polyimide film with a special silicone adhesive. Outstanding thermal resistance and excellent insulating properties, this tape is used where toughness, puncture resistance and flame retardance are important. For protection of gold fingers during wave soldering, it can also be used as a ground barrier and phase insulation in high performance coils, as an outer wrap on small bobbin wound coils and on form wound coils for traction motors.
