Micanite is the name given to sheet material which is made up of fine mica lamellae, called “Mica Splittings”, bonded together by a variety of bonding agents such as Shellac, epoxy, alkyd or silicone, in order to obtain particular characteristics for specific uses. Variations can be made in the method of manufacture, the types of Mica, and the type of quantity of bonding material used to form thick or thin, stiff or flexible products in the form of sheets, webs or ribbons and also moulded articles.

PNR Micanite Product Range


Moulding Micanite Sheet material is usually made from layers of clear mica splittings held together by a modified shellac bond in order to have the necessary flexibility when warmed for moulding and the mechanical rigidity when set thereafter. Moulding micanite is used in the manufacture of commutator vee-rings, end caps, tubes, brushes etc.


Heat Resisting Micanite Sheet is made from high quality mica splittings with the shellac bond being kept low. The material is made available from both Muscovite mica and Phlogophite mica where the maximum working temperature are approximately 600°C and 900°C respectively. It used in the manufacture of wide variety of both domestic and industrial heating applications.


Flexible Micanite Sheet is made from clear mica splittings bonded together These sheets may or may not contain re-enforcing material These materials are quite flexible and can be cut to desired sizes to permit winding or wrapping into place without heating. Flexible Micanite sheet is used in electric appliances.

Commutator Vee Rings are made from the high quality moulding micanite which is made at our works. The hand moulded process gives excellent results but is a very labour intensive and slow method of production. It therefore tends to be used mostly for very large rings where quantities are relatively small.


Punched Segment Mica product is prepared by pasting Muscovite splittings with an alkyd varnish as a binder in a little amount and processing at a very high temperatures and high pressure and then grinded.


PNR has perfected the ability to make mica tubes of the very highest quality from Micanite. Specially selected grades of Splittings are used for this purpose in order to ensure the possibility of being able to roll even the smallest diameter tubes. Micanite tubes and bushes are used in electrical switchgear, control gearas,large variable resistances, brush holder assemblies and commutator.


Mica Washers made from our own Heat Resisting Micanite and Moulding Micanites are used in electro-magnets, microsensitive control gear and for many other purposes. They are either cut or die stamped from the sheet material according to the customer's drawing.


Mica Insulation Plate are designed and manufactured for use in extreme conditions and have very good properties like heat retarding, flame resisting, low thermal conductivity, good electrical insulation, high mechanical strength, non toxic and non hazardrous. It is classified by the mica type mainly Muscovite and Phologophite. It is mainly used in furnace lining, resistor heat dissipaters, insultion of heated hydraulic presses, induction furnace etc.


All the items can be supplied in any size, thickness and shape according to the customer’s specification.
