Resin Rich Glass Mica Tape

Ruby Mica° Glass / Mica Resin-Rich Tape is a lamination of uncalcined muscovite mica paper with glass cloth. A thermo setting tri-functional epoxy novolac resin is used as a bonding agent making it a Class F insulation product. The tape is tack-free in cold conditions. An LDPE film interleaving is used to prevent the tape interlayers from sticking to each other during ambient temperature fluctuations.

Our resin-rich mica tapes make the coils electrically-stronger, and gives superior coil-heat dissipation capabilities.

The homogeneous insulation produced after pressing and curing has a temperature-index of at least 155.

Application

Main slot wall insulation of bars / coils in HT motors and turbo-generators. Its molded rigid laminate form can also be used to insulate commutators and form electro-thermal sleeve insulation for various applications.
