Molding Micanite Sheets


Molding Micanite Sheets

We bring forth flawless Molding Micanite Sheets in a wide range of specifications. Molding Micanite Sheets is a lamination is made up of two layers of fine muscovite mica spitting with glass cloth. They are bonded together using a B stage epoxy resin. Molding Micanite Sheets facilitate end-winding on high voltage machines. They provide excellent corona-resistant insulation and are capable of withstanding high voltage partial discharge when fully cured to form rigid laminates.

 

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 180oC. Whereas, shellac resin-bonded sheets stay rigid at room-temperature and have to be preheated to gain flexibility before curing it completely at 150 oC to form a rigid and robust insulation.

 

Application : Armature coil ground-insulation, armatures slots, windings and coil insulation, end-winding turn insulation, bracing rings and V-Ring manufacturing.
