It transmits and reflects light to produce decorative effects and also prevents penetration of "SUN" rays, moisture, heat, gases etc. on the surface on which it's coated. It produces stiffening effect of calendered sheets. It has very high lubrication value and can be used as : High temperature grease, mould release etc. in rubber & plastics Dusting surface. Anti Friction powder of compounds. It produce lifting effects in liquid products due to low specific gravity and as such, remain uniformly dispersed over the surface of liquid vehicles. It has excellent di-electric & thermal insulation properties. It has very little abrasive effect and can easily get wetted by resin and dyes. It has an excellent anti-sticking property and as such, during vulcanization, it prevents sticking and movement of sulphur, at the same time, it permits the air bubbles to escape.

Our company is a top notch Manufacturer, Supplier and Exporter of Mica Flakes from Jharkhand, India. We package the Mica Flakes in high-grade materials so there is no loss in the quality or properties during storage or transportation. We are proficient in handling bulk orders of Mica Flakes and ensuring their timely delivery. Highlights : Mica Natural Flakes are made out of selected Mica Scrap, Dried, and Screened & Sheared.Process : First the selected mica scrap is dried to avoid any humidity. Secondly mica scrap is screened to avoid dust. Thirdly all the foreign particles like biotite (black Mica), quartz, straw, bamboo (organic & inorganic materials) are removed by hand picking. Here we again screen the material. Now the material is ready to be sheared (in grinding machine). Grinded material is then directly through blower sucked & blown in a round screen which is having blower to separate dust from the grinded material & the 8 mesh screen size to bring down the 2-8mesh Natural Muscovite Ruby Mica Flakes. In this case, mica scrap & waste are pulverized by mechanical grinders such as high speed hammer, rod, attrition, mills or cage distintefrators which reduce them to flakes and powder of different mesh sized ranging from 2 to 300 meshes. These flakes and powder are classified into various mesh sizes with the help of sieve classifiers. Coarse Mica Flakes: Plus 6 mesh, having a bulk density of 0.17kg/ltr. Have high percentage of relatively large flakes for sealing large openings. Medium coarse mica flakes: Plus 10 meshes having a bulk density of 0.18kg/ltr. Area generally used to combat mild circulation losses in porous information Fine Mica flakes: Plus 20 mesh having a bulk density of 0.20 kg/ltr is particularly used when a sealing agent is needed small enough to allow the mud to pass through a shaker screen without interfering with the operation. Specifications : Uses : Natural muscovite mica flakes are used as raw mica material for regrinding, micronizing, sheet and pulp manufacturing for mica paper. Small sized of mica flakes are required for roofing felt industries, decorative purpose & mica board manufacturing to insulate the wall of houses for preventing noise, heat & ultra violet rays. Packing : It depends up to the customer. Generally it's packed in HDP, jute or paper bag of 10,25, 50kgs. Delivery : Minimum one 20' T.E.U. (full container load of 20 ton) Inspection : Can be carried out by the buyer or the buyer nominated independent inspection agency before shipment at our works Capacity : In our machine we can produce 10 tons per duly screened.

We extract the mica using advanced machinery and latest mining techniques. Customers from all over the world can avail Raw Mica in bulk from us at highly affordable rates. Highlights : Mica is a group mineral & having Electrical & Mechanical strength, heat and moisture resistance, elastically, chemical inertness and high temperature stability. Out of several varieties of mica, the Ruby Muscovite Mica and Phlogopite Amber Mica are most useful to electrical industry The chemical formula of Muscovite Mica is K2O, 3Al2 O3, 6SIO2 and that of Phlogopite Mica is K2O, 6 MgO, Al2O3, 6SiO2, 2H2O The Muscovite is either colorless or some what Red or Green. Phlogopite is mostly dark in color, golden, brown & black Mica is found in nature with inclusion of Quarts, Feldspar and few other Minerals. Pagmatites are the chief source of commercial muscovite mica. After mining, the raw mica is graded and cleared from large inclusion. It is then cleaved into thin sheets by splitting. Mica is being used in various forms such as: Block Mica, Mica Washer, Mica Scrap, Mica Flakes, Mica Powder, Condenser Mica, Mica Disc, Built Up Mica etc. Mica has many uses according to its quality, for example superfine clear mica is used in condensers for Radio, Radar and Guided Missile.
