Product Description
Hot Molding Mica Splitting Sheet
Ruby Mica Hot Molding Micanite Sheet is made by depositing highly-flexible, thin films of high-quality muscovite mica splittings on top of each other till the required thickness is attained.
Currently, hot molding micanite sheet is available with two choices of binding agent. Alkyd resin-bound sheets stay flexible at room-temperature and is cured completely at 180C. Whereas, shellac resin-bonded sheets stay rigid at room-temperature and have to be preheated to gain flexibility before curing it completely at 150C to form a rigid and robust insulation.
Application
Armature coil ground-insulation, armature slots, windings and coil insulation, end-winding turn insulation, bracing rings and V-Ring manufacturing.
