1. MUSCOVITE MICA FLAKES FOR PEARLESCENT PIGMENTS
MUSCOVITE MICA FLAKES of superior quality having low iron contents are used in large proportion in production of PEARLESCENT PIGMENTS, because of its reflective and refractive properties and its ability to reproduce artificially a "mother of pearl" or nacreceous colours from silver white through all shades of the rainbow varying from a silky lustre to a glittering sparkle. Mica have high refractive index (greater than sparkle. Mica have high refractive index (greater than 2.5) and a good chemical, mechanical and thermal stability.

2. MICA FLAKES FOR OIL-WELL DRILLINGS/MUD CHEMICAL
MICA FLAKES have been preferably used in water-based and oil-well drillings operations as an additive mud chemical to prevent loss of circulation and seepage. Mica is specially added to seal-off the lost circulation zones. The platy structure of mica facilitates the overlapping of particles to form a layer or wall and acts as a sealent that bridges the openings. The use of Mica helps to seal porous formations and contributes to regain circulation keeping the solids in suspension.

MICA POWDER

1. MICA FOR GYPSUM PLASTER BOARDS
Muscovite dry ground mica is light in weight, non-combustible, free flowing, chemically inert, resilient and non-abrasive. It have good thermal insulation properties and an excellent characteristics for sound absorption. Low shrinkage and coefficient of expansion, good dimensional stability, temperature stability, and extremely low water absorption are some of its additional outstanding features. All these properties makes mica an ideal product for use as a filler in light-weight fire-resistant pre-fabricated gypsum wallboard slabs and panels for building constructions, in place of asbestos, where thermal insulation and acoustic properties are of particular importance.

2. MICA FOR WELDING ELECTRODES
Muscovite dry ground mica is well recognised for use in mild steel rutile based welding electrodes. In the manufacture of welding electrodes a core of steel wire is coated uniformly with a 'flux' comprising mica as a lagging compound. Mica is added to the 'flux' with which welding electrodes are coated as binders, extrusion agents and pigments to aid slag formation, weldpool protection and arc stabilisation. The mica coating provides two distinct types of protection to the welding rods. Firstly, it serves in forming a fusible slag and a good seal at the fusion zone on the arc. Secondly, it resists the action of heat, gaseous and other surrounding atmospheric oxidization. In fact, it is the nature of mica coating that largely determines the quality of a welding electrodes.

3. MICA FOR WALLBOARD JOINT CEMENTS
Dry ground muscovite mica is effectively used a cost-effective filler and surfacing agent in wallboard joint cement compounds to fill the joints between panels of wallboards, as well as, in the finished coating of ceilings in building constructions, because of its many functional and morphological surface characteristics. In this particular application, mica acts as a reinforcing pigment reducing penetration into porous surfaces, improving mixing and trowelling properties of jointing cements. High heat resistance, excellent mechanical and thermal strength, low moisture absorption, high surface leakage resistance, unusual chemical resistance and non-hygroscopic properties are some of the distinctive mica properties which makes it an useful ingredient for use in the above applications.

4. MICA FOR ASBESTOS-FREE BRAKE LININGS
Mica has an outstanding electrical, thermal, mechanical and chemical properties. High heat resistance, excellent mechanical and thermal strength, low moisture absorption, high surface leakage resistance, unusual chemical resistance and non-hygroscopic properties are some of the most distinctive properties of mica. Mica particles are stronger than iron and are not brittle like other inert inert material. It serves to reinforce, stiffen, harden and strengthen the product and prevent microscopic ruptures, reduce warping, lower thermal expansion and conductivity. During the mixing process, the use of mica helps to achieve a more homogeneous mix. Due to platy nature and surface characteristics of mica, it tends to lock together under compression during wet or dry, cold or hot processes to form an effective plateform for the matrix of other materials in the formulation. As such, the benefit of mica for use as friction materials for asbestos-free brake linings, brake shoes, clutch discs, etc. is well recognised.

5. MICA POWDER FOR RUBBER & TYRE APPLICATIONS
It is suitably used as an anti-blocking, anti-sticking and anti-friction agents between the inner rubber and castings of rubber tyres for aeroplanes, automobiles and motor bikes. It is primarily used as a dusting agent and mold lubricants to prevent massing and adhesion of the rubber compounds during vulcanization and acts as a separating factor for the cores of the outer sheath. Besides, it prevents movement of sulphur while permitting air and moisture to escape during curing and helps create a uniform pore structure that leads to improve resiliency and reduced shrinkage.
