Mica are sheet silicates historically significant for their ability to be split into large, thin sheets that are uniquely useful for their electrical, thermal, and mechanical properties. They have high electrical and thermal insulating properties; they are resistant to chemical attack; they can be split into transparent or optically flat films; and they can be cut or stamped to shape. Uses of mica: 1- Joint cements: muscovite is used in drywall joint compounds, where it contributes to consistency and workability, smooth surface finish, and resistance to shrinkage and cracking. 2- Coatings Fine-ground, -325 mesh and micronized mica grades are used in paint as a pigment extender and for dry film reinforcement. The inert, platy mica improves suspensi on stability, controls film checking, chalking, shrinkage, and blistering, improves resistance to weathering, chemicals, and water penetration, and improves adhesion to most surfaces. Coarser grinds are used in textured paints, and wet-ground mica is used in high quality exterior house paints. High aspect ratio grades are preferred for porous surface sealers to seal pores, control penetration, and reduce sagging and film cracking. 3- Plastics Finely ground, -325 mesh and micronized micas are used in plastics to improve electrical, thermal, and insulating properties. Mica is considered the most effective mineral for reducing warpage and increasing stiffness and heat deflection temperature in plastics. In general, mica reinforces crystalline better than amorphous polymers. Best results are obtained with nonpolar polymers when mica is pretreated with a coupling agent to improve wetting. Mica is used in both thermoplastics and thermosets. Its largest single use is in polyolefins, even though it requires stabilizers to prevent degradation of polypropylene. 4- Drilling fluids Coarse, hammermilled (+10 mesh) mica is used in waterbased oilwell drilling fluids to prevent fluid loss into porous rock formations.

MICA SCRAP / MICA CHIPS We are one of the leading manufactures and suppliers of mica scrap in India which is widely used for various industrial purposes. Irregular clumps of raw mica obtained from mines are called mica scrap, having an area between 1/2" and 1 1/2". We supply mica scraps which are substantially free from mineral impurities, non mineral impurities and other foreign inclusions. These are obtained from systematic and automated chemical refining processes. Our mica scrap is widely used in the manufacture of mica paper, mica plates, mica flakes and mica powder. We mainly export high quality scrap by removing dust, stone and other particles to plants all over the world. Mica Scraps can be classified into different categories based upon temperature, size, and purity requirements. They are available in Muscovite, Phlogopite and Biotite. Several sizes are available like -1/6" & up, 1/3" & up, 1/2"& up, 3/4" & up, 1" & up. White mica is well known for its shine and color, well suited for the production of paper and powder. This white mica scrap is good for calcinations as it cannot sustain its properties at a temperature of 800-900 degree Celsius." Features of Mica Scrap / Mica Chips High quality and strength These scraps are extracted from authentic mines Free from contamination Contains good chemical and physical properties Obtained from automated chemical and refining process Smooth, soft and cost effective Applications of Mica Scrap / Mica Chips Mine scrap is primarily used as raw material for ground mica for industrial uses such as paints electrodes etc and for manufacturing of mica paper or reconstituted mica as a basic raw material. Used in the manufacture of Mica Powder, Flakes, Paper. Lubricants and roofing materials. Used as filler in rubber Plants Welding Electrodes, Cables and Wires. Acoustical Plaster.
