Mica paper tape for high voltage motor and generator stator windings

Improved functional properties and process simplification now can be attained through the use of solventless, resin-filled Mica Mat tapes used for high voltage ground insulation. Previously, all B-staged resin-filled tapes composed of either flake mica or mica paper have been manufactured with resin/solvent solutions because the solvents were necessary to reduce the viscosity of the resin for impregnation and to soften the tapes for application. However, when solvents are used, removal of them is difficult, costly, and complete removal is often virtually impossible.
