The natural structure stability feature of mica makes it perfect with outstanding features of low leakage, great stability under increasing temperature, high insular strength, low rate of solar impurities and reasonable admittance factor. For These outstanding features, mica is most suited for use in thermionic valve bridges, cathode ray tube assemblies, condenser plates, domestic elements, stove plates and washers built up to any thickness. In almost all these applications, mica is die-punched and used as such, or with a coating.

Our range of production offers a wide variety of fabricated mica. You can choose from our available sizes or we can customize as per customer’s drawings.

CRIMPED / CORRUGATED MICA Corrugated Mica is made from Muscovite mica of Jharkhand origin.It can withstands high temperatures of above 700°C. This mica is supplied as per customer's specification. The main use of this type of mica is in soldering irons.

TRANSISTOR PARTS Power transistors and diodes need an insulation to prevent excessive heat reducing their performance. Precision punched mica washers help the transistor to be insulated from the chassis and to dissipate heat away from the transistor and other semi-conductors.

MICA FOR LIQUID LEVEL INDICATORS Mica is unaffected by high temperature and high pressure. It is an ideal optical medium for checking the measurements in boilers for liquid level and pressure of steam.

MICA WASHERS Mica washers are mica dics of inferior quality with round opening in the centre, which can be bonded by shellac or epoxy into considerable lengths. Maximum use is in railways.

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

WINDOW MICA Window Mica is used as a see-through medium for kerosene stoves, petromax lamps, furnaces etc due to thermal transparency and insulation.

WRAPPER MICA Wrapper mica is made by die-cutting of mica thins, it is corrugated and eventually used in wrapping the heating element of soldering iron.

STRAINER CORE Sheet mica having 22 to 93 holes are used as strainers in brass, bronze, aluminium sand castings. Mica strainers, helps to eliminate getting casts, dross.

CUT MICA DISCS Die cut or lathe cut round discs are used in liquid level indicators, breathing apparatus, communication devices, fuses, etc.

TRIMMER MICA Stacked mica dielectric capacitance units, between two spring nonferrous metal conducting plates, mounted within a ceramic container, or on a ceramic base.

BACKING MICA Baking Mica are small cut pieces of mica to be used on both sides of silver mica, to give mechanical strength to mica stacks for building mica capacitors. s
