This tube is made from mica splitting for use in standing temperature of upto 600 C in a very small size.

Made of stacked mica dielectric capacitance units, between two spring nonferrous metal conducting plates ; mounted within a ceramic container, or on a ceramic base. Adjusting screw provides variable compression on the formed metal plate separation

Made by die cutting of thin mica films, it is screen printed with silver ink to be used as an electrode in mica capacitors.

This product is prepared by pasting muscovite splittings with an alkyd varnish as binder in a small amount and processing at a very high temperature and pressure and then ground.

Natural Mica Washers are circular punched and stamped natural mica parts with round openings in the center suitable for electrical and electronic application. Such natural mica washers can also be bonded into considerable lengths with shellac, epoxy or silicone binders to form a solid roll which is then called Bonded Mica Washers. Maximum use is in railways and grid resistors. Based on customer specifications, Mica washers can be punched, stamped and/or machined into different sizes, shapes and thickness for various temperature ranges

Sheet mica having 22 to 93 holes are used as strainers in brass, bronze, aluminium sand castings. Mica strainer, acting as both choked and strainer during pour, helps to eliminate getting casts, dross, contaminated, reduces polishing belt costs, and produces a better and brighter casting. Being inorganic, strainer is easy to place over the sprue hole.

Heat Resisting Micanite is made from high quality mica splittings with the shellac bond being kept low. The material is made available from both muscovite and phlogopite Mica where the maximum working temperatures are approximately 600 C and 900 C respectively. Heating Resisting Micanite is used in the manufacture of a wide variety of both domestic and industrial heating applications such as electric iron elements, wound heater elements, cylindrical resistance heaters etc.

Flexible Micanite is made from clear mica splittings bonded together with special flexible bonds which permit forming down to small radii while cold. These materials are quite flexible and can be cut to desired sizes to permit winding or wrapping into place without heating. It is used for a wide variety of slot insulations and field coils and generally where cold wrapping of insulation is required; as well as in various electrical appliances such as generator, electric furnace, magnetic coil, coil insulation, etc.

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.

Pieces of high quality Mica having thickness generally less than 2 mils are classified as Condenser Films.

OTC produces all sizes and quality of Condenser Films. Special care is taken to keep the films free from V-cuts, half layers, cracks and finger prints. PPA passed Condenser Films are also made to meet specific customer needs.

We can meet all requirement of condenser films as per buyers specification.

Application :These Films are used in the manufacture of Silver Mica Plates used in Mica Capacitors.

Most appropriately used for warming and heating applications in toasters, roasters, kettle, flat irons, hair dryers, popcorn makers, cookers, ovens, percolators, griddles, stoves and other electrical appliances/heaters. Also used in heating elements for strip heaters and band heaters where it is sheathed in stainless steel or brass or rust-resistant steel.

Washers made from our own heat resisting and moulding micanites are used in electro-magnets, micro-sensitive control gear and for many other purposes. They are either cut or die stamped from the sheet material according to the customers' drawings.

Apart from vee rings a variety of other shapes are moulded from micanite such as end caps, channels and troughs, angle pieces, etc. and these are used for a wide variety of applications. The manufacturing methods are similar to those used in the manufacture of vee rings.

This material is usually made from layers of clear Indian 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, bushes, etc

Mica being unaffected by high temperature and high pressure, is an ideal optical medium for checking the measurements in boilers for liquid level and pressure of steam.

The Electronics Industries has a great use of Mica washers and insulators for both electrical and heat insulation. These various shapes of transistor Mica can increase the efficiency of products due to the excellent properties of mica.

In the form of bridges or spacers, sheet mica is used in thermionic vacuum tubes, and these serve to hold the tube elements in position, insulated from each other and at uniform distances.

Micanite or Built up Mica is an artificially built up mica, and with advent of a variety of binding materials, great progress has been made in its manufacture. Mica films are placed with alternate layers of binding materials like shellac, alkyd, epoxy or silicone and then pressed and baked. Micanite is in common use now. It is convenient to cut or punch micanite according to requirements.
