We offer a complete product range of Ground Mica, Processed Mica and micanite

Ground Mica

We offer ground mica. By far the largest use of mica, both quantitative and application wise, is in the form of ground mica. It is prepared from grinding and breaking of mica scrap or waste namely by dry ground process. The production is economically carried out in high speed rotary hammer mills or pulverisers transforming into mica flakes and mica powders of different particle sizes. Meticulous care and precaution is taken to avoid deterioration of its natural brilliance, colour and properties. By virtue of its outstanding characteristics and exceptional values, ground mica have shown phenomenal growth rendering extensive usage in many diversified industries, in certain spheres as vital and as significant as one could well imagine.

Processed Mica

We offer processed mica. The crystals of mica extracted from the mines are in the form of rough lumps of irregular shape, size and thickness associated with impurities and structural imperfections. They have to undergo a lengthy operation of cutting, cleaning, sorting and processing from crude to commercial quality which involves skilled labour and intensive technique.

Micanite

We offer micanite. micanite or built-up mica are manufactured with layers of overlapping mica splittings laid-up by hand or mechanical process and bonded with selected resins (such as shellac, epoxy, alkyd, silicone or other agents) in order to obtain characteristics for specific end-uses. It is then cured under high heat and pressure. Diverse range of composite binders are available according to temperature resistance and thermal insulation class namely, 'b' (130c), 'f' (155c) and 'h' (180c) to match different applications.

Fabricated Mica

We offer fabricated mica. The term fabricated mica applies to cutting, stamping and punching of natural sheet mica to a specified size, shape and thickness within close dimensional tolerances for electrical and electronic end-uses. Most of the fabricated mica components are custom built against provided specifications and drawings which are subject to change from part to part. The fabrication is performed by using foot or power presses with the help of compound diestools. The mica may also be hand-sheared, drilled or lathe-turned. They are produced into innumerable designs each differing in size, pattern, thickness and quality from one another.

Mica Paper

We offer mica paper. Mica paper is manufactured from superior quality mica scrap as a principal raw material by calcined (thermo-chemical) and uncalcined (hydro-chemical) process in the form of continuous rolls. Mica paper being an artificial mica-based reconstituted product, it retains the essential heat resistivity and electrical characteristics of natural mica. Furthermore, it is cost effective and more homogeneous having greater consistency of thickness and uniformity of properties.

Mica Blocks

We offer mica blocksknife or scissor dressed sheet mica with irregular shape and a minimum thickness of 0.18 mm (0.007 inch or 7 mils) are called mica blocks. Block mica are classified into thirteen size groups (ranging from ooee special down to no. 7) and obtained in size as large as 30 - 35 cm sq. (12 - 14 inches sq.) beyond which is practically rare and far too expensive. It is available in sheets with both random (natural) and calibrated thickness as per demand. After undergoing size and quality grading, mica blocks are exported.

Mica Heating Elements

We are offering mica heating elements, mica heating elementshigh resistance nichrome or electrical wire is winded around natural mica providing quality insulation for use as heating elements in irons, toasters, kettles, rice cookers and other electric heating appliances. It is available in all usual sizespatterns in different voltage and wattage as per specifications.

Mica Washer

Mica washernatural mica washers are circular punched and stamped natural mica parts with round openings in the center suitable for electrical and electronic applications. 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.

Mica Spacers

We are offering mica spacers, mica spacersin the form of bridges or spacers, it is used in radio and television vacuum tubes. These spacers serves to hold the tube elements in position, insulated from each other and at uniform distances.

Mica Scrap

We offer mica scrapmica recovered by means of hammer crushing, processing and screening of crude mica having an average area between 12 to 50 mm sq. (12 to 2 inch sq.) is defined as mica scrap. All mica scrap are substantially free from mineral and non-mineral impurities as well as other foreign inclusions. It is exported to plants all over the world and finds paramount use as a primary raw material in the manufacture of mica paper or re-constituted mica. Domestically, mica scrap is used as a basic material for the manufacture of ground mica flakes and powders.
