NBR-Mica Tape for Electromagnetic Wire Wrapping (NBR-5441-1)

5441-1 Mica tapeMica tape for electromagnetic wire wrappingMica paper as the base material, reinforced by polyester film on one side or both, felted by modified heat-resistant epoxy resin adhesive or other heat-resistant adhesive. The insulating material, mica tape, is manufactured through the process of backing and incising.Between 0.07 to 0.10mm thickness, this kind of mica tape characterized by excellent plasticity and storage stability under normal conditions, can be used to single electromagnetic wire wrapping of all kinds of large and medium-sized HV motors, generators and transformers.
