Ruby Mica Co. Ltd


Resin Rich Mica Tape




Our company holds expertise in manufacturing, exporting and supplying excellent grade Resin Rich Mica Tape. Designed with utmost precision in numerous specifications, the Resin Rich Mica Tape finds application in HT motors and turbo-generators for main slot wall insulation. Its molded rigid laminate form can also be used to insulate commutators and form electro-thermal sleeve insulation for various applications. Our Resin Rich Mica Tape makes the coils electrically stronger and gives superior coil-heat dissipation capabilities. We provide Resin Rich Mica Tape at very affordable prices.

 

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

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.
