Epoxy mica plates for commutators are hard plate-type insulating materials in which epoxy adhesive is used to bond mica papers and then bake them accordingly. They have high mechanical strength and good thickness uniformity and are mainly suitable for insulation between commutators' copper plates in Class F DC motors and used as insulating liners for other electrical machines and appliances.
